/**
* morebits.js
* ===========
* A library full of lots of goodness for user scripts on Wikipedia.
* (It should work on other MediaWiki wikis as well, despite some Wikipedia-specific object naming.)
*
* The highlights include:
* - QuickForm class - generates quick HTML forms on the fly
* - Wikipedia.api class - makes calls to the Wikipedia API (or the API of any MediaWiki wiki)
* - Wikipedia.page class - modifies pages on the wiki (edit, revert, delete, etc.)
* - MediaWiki class - contains some utilities for dealing with wikitext
* - Status class - a rough-and-ready status message displayer, used by the Wikipedia classes
* - SimpleWindow class - a wrapper for jQuery UI Dialog with a custom look and extra features
*
* Dependencies:
* - The whole thing relies on jQuery. But most wikis should provide this by default.
* - QuickForm, SimpleWindow, Status, and the portlet stuff rely on the "morebits.css" file for their styling.
* - SimpleWindow relies on jquery UI Dialog (ResourceLoader module name 'jquery.ui.dialog').
* - QuickForm tooltips rely on Tipsy (ResourceLoader module name 'jquery.tipsy').
* For external installations, Tipsy is available at [http://onehackoranother.com/projects/jquery/tipsy].
* - To create a gadget based on morebits.js, use this syntax in MediaWiki:Gadgets-definition:
* * GadgetName[ResourceLoader|dependencies=jquery.ui.dialog,jquery.tipsy]|morebits.js|morebits.css|GadgetName.js
*
* Most of the stuff here doesn't work on IE < 9. It is your script's responsibility to enforce this.
*
* This library is maintained by the maintainers of Twinkle.
* For queries, suggestions, help, etc., head to [[Wikipedia talk:Twinkle]] on English Wikipedia [http://en.wikipedia.org].
* The latest development source is available at [https://github.com/azatoth/twinkle/blob/master/morebits.js].

/**
* **************** twAddPortlet() ****************
*
* Adds a portlet menu to one of the navigation areas on the page.
* This is necessarily quite a hack since skins, navigation areas, and
* portlet menu types all work slightly different.
*
* Available navigation areas depend on the script used.
* Monobook:
* "column-one", outer div class "portlet", inner div class "pBody". Existing portlets: "p-cactions", "p-personal", "p-logo", "p-navigation", "p-search", "p-interaction", "p-tb", "p-coll-print_export"
* Special layout of p-cactions and p-personal through specialized styles.
* Vector:
* "mw-panel", outer div class "portal", inner div class "body". Existing portlets/elements: "p-logo", "p-navigation", "p-interaction", "p-tb", "p-coll-print_export"
* "left-navigation", outer div class "vectorTabs" or "vectorMenu", inner div class "" or "menu". Existing portlets: "p-namespaces", "p-variants" (menu)
* "right-navigation", outer div class "vectorTabs" or "vectorMenu", inner div class "" or "menu". Existing portlets: "p-views", "p-cactions" (menu), "p-search"
* Special layout of p-personal portlet (part of "head") through specialized styles.
* Modern:
* "mw_contentwrapper" (top nav), outer div class "portlet", inner div class "pBody". Existing portlets or elements: "p-cactions", "mw_content"
* "mw_portlets" (sidebar), outer div class "portlet", inner div class "pBody". Existing portlets: "p-navigation", "p-search", "p-interaction", "p-tb", "p-coll-print_export"
*
* NOTE: If anyone is brave enough to reuse this directly, please shoot
* me a note. Otherwise I might change the signature down the line and
* your script breaks. Amalthea.
*
* @param String navigation -- id of the target navigation area (skin dependant, on vector either of "left-navigation", "right-navigation", or "mw-panel")
* @param String id -- id of the portlet menu to create, preferably start with "p-".
* @param String text -- name of the portlet menu to create. Visibility depends on the class used.
* @param String type -- type of portlet. Currently only used for the vector non-sidebar portlets, pass "menu" to make this portlet a drop down menu.
* @param Node nextnodeid -- the id of the node before which the new item should be added, should be another item in the same list, or undefined to place it at the end.
*
* @return Node -- the DOM node of the new item (a DIV element) or null

* Callers should set Wikipedia.actionCompleted.notice and Wikipedia.actionCompleted.redirect

*
* Each of the callback functions takes one parameter, which is a

* Callback functions may invoke any Wikipedia.page prototype method using this reference.
*
* Constructor: Wikipedia.page(pageName, currentAction)
* pageName - the name of the page, prefixed by the namespace (if any)
* (for the current page, use mw.config.get('wgPageName'))
* currentAction - a string describing the action about to be undertaken (optional)
*
* load(onSuccess, onFailure): Loads the text for the page
* onSuccess - callback function which is called when the load has succeeded
* onFailure - callback function which is called when the load fails (optional)
* XXX onFailure for load() is not yet implemented – do we need it? -- UncleDouggie
* probably not -- TTO
*
* save(onSuccess, onFailure): Saves the text for the page. Must be preceded by calling load().
* onSuccess - callback function which is called when the save has succeeded (optional)
* onFailure - callback function which is called when the save fails (optional)
* Warning: Calling save() can result in additional calls to the previous load() callbacks to
* recover from edit conflicts!
* In this case, callers must make the same edit to the new pageText and reinvoke save().
* This behavior can be disabled with setMaxConflictRetries(0).
*
* append(onSuccess, onFailure): Adds the text provided via setAppendText() to the end of the page.
* Does not require calling load() first.
* onSuccess - callback function which is called when the method has succeeded (optional)
* onFailure - callback function which is called when the method fails (optional)
*
* prepend(onSuccess, onFailure): Adds the text provided via setPrependText() to the start of the page.
* Does not require calling load() first.

* onFailure - callback function which is called when the method fails (optional)

* getPageName(): returns a string containing the name of the loaded page, including the namespace
*
* getPageText(): returns a string containing the text of the page after a successful load()
*
* setPageText(pageText)
* pageText - string containing the updated page text that will be saved when save() is called
*
* setAppendText(appendText)
* appendText - string containing the text that will be appended to the page when append() is called
*
* setPrependText(prependText)
* prependText - string containing the text that will be prepended to the page when prepend() is called
*
* setEditSummary(summary)
* summary - string containing the text of the edit summary that will be used when save() is called
*
* setMinorEdit(minorEdit)
* minorEdit is a boolean value:
* true - When save is called, the resulting edit will be marked as "minor".
* false - When save is called, the resulting edit will not be marked as "minor". (default)
*
* setPageSection(pageSection)
* pageSection - integer specifying the section number to load or save. The default is |null|, which means
* that the entire page will be retrieved.
*
* setMaxConflictRetries(maxRetries)
* maxRetries - number of retries for save errors involving an edit conflict or loss of edit token
* default: 2
*
* setMaxRetries(maxRetries)
* maxRetries - number of retries for save errors not involving an edit conflict or loss of edit token
* default: 2
*
* setCallbackParameters(callbackParameters)
* callbackParameters - an object for use in a callback function
*
* getCallbackParameters(): returns the object previous set by setCallbackParameters()
*
* Callback notes: callbackParameters is for use by the caller only. The parameters
* allow a caller to pass the proper context into its callback function.
* Callers must ensure that any changes to the callbackParameters object
* within a load() callback still permit a proper re-entry into the
* load() callback if an edit conflict is detected upon calling save().
*
* getStatusElement(): returns the Status element created by the constructor
*
* setFollowRedirect(followRedirect)
* followRedirect is a boolean value:
* true - a maximum of one redirect will be followed.
* In the event of a redirect, a message is displayed to the user and
* the redirect target can be retrieved with getPageName().
* false - the requested pageName will be used without regard to any redirect. (default)
*
* setWatchlist(watchlistOption)
* watchlistOption is a boolean value:
* true - page will be added to the user's watchlist when save() is called
* false - watchlist status of the page will not be changed (default)
*
* setWatchlistFromPreferences(watchlistOption)
* watchlistOption is a boolean value:
* true - page watchlist status will be set based on the user's
* preference settings when save() is called
* false - watchlist status of the page will not be changed (default)
*
* Watchlist notes:
* 1. The MediaWiki API value of 'unwatch' isn't used here because it seems to behave
* the same as 'nochange'. Not sure why we would want this option anyway.
* 2. If both setWatchlist() and setWatchlistFromPreferences() are called,
* the last call takes priority.
* 3. Twinkle modules should use the appropriate preference to set the watchlist options.
* 4. Most Twinkle modules use setWatchlist().
* setWatchlistFromPreferences() is only needed for the few Twinkle watchlist preferences
* that accept a string value of 'default'.
*
* setCreateOption(createOption)
* createOption is a string value:
* 'recreate' - create the page if it does not exist, or edit it if it exists
* 'createonly' - create the page if it does not exist, but return an error if it
* already exists
* 'nocreate' - don't create the page, only edit it if it already exists
* null - create the page if it does not exist, unless it was deleted in the moment
* between retrieving the edit token and saving the edit (default)
*
* exists(): returns true if the page existed on the wiki when it was last loaded
*
* lookupCreator(onSuccess): Retrieves the username of the user who created the page
* onSuccess - callback function which is called when the username is found
* within the callback, the username can be retrieved using the getCreator() function
*
* getCreator(): returns the user who created the page following lookupCreator()
*
* patrol(): marks the page as patrolled (only when "rcid" is present in the query string)
*
* move(onSuccess, onFailure): Moves a page to another title
*
* deletePage(onSuccess, onFailure): Deletes a page (for admins only)
*
