/**
* morebits.js
* ===========
* A library full of lots of goodness for user scripts on MediaWiki wikis, including Wikipedia.
*
* The highlights include:
* - Morebits.quickForm class - generates quick HTML forms on the fly
* - Morebits.wiki.api class - makes calls to the MediaWiki API
* - Morebits.wiki.page class - modifies pages on the wiki (edit, revert, delete, etc.)
* - Morebits.wikitext class - contains some utilities for dealing with wikitext
* - Morebits.status class - a rough-and-ready status message displayer, used by the Morebits.wiki classes
* - Morebits.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.
* - Morebits.quickForm, Morebits.simpleWindow, and Morebits.status rely on the "morebits.css" file for their styling.
* - Morebits.simpleWindow relies on jquery UI Dialog (ResourceLoader module name 'jquery.ui').
* - Morebits.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=mediawiki.user,mediawiki.util,jquery.ui,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].

* **************** Morebits.wiki.page ****************
* Uses the MediaWiki API to load a page and optionally edit it, move it, etc.
*
* Callers are not permitted to directly access the properties of this class!
* All property access is through the appropriate get___() or set___() method.
*
* Callers should set Morebits.wiki.actionCompleted.notice and Morebits.wiki.actionCompleted.redirect
* before the first call to Morebits.wiki.page.load().
*
* Each of the callback functions takes one parameter, which is a
* reference to the Morebits.wiki.page object that registered the callback.
* Callback functions may invoke any Morebits.wiki.page prototype method using this reference.
*
*
* HIGHLIGHTS:
*
* Constructor: Morebits.wiki.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)
*
* onSuccess and onFailure are callback functions called when the operation is a success or failure
* if enclosed in [brackets], it indicates that it is optional
*
* load(onSuccess, [onFailure]): Loads the text for the page
*
* getPageText(): returns a string containing the text of the page after a successful load()
*
* save([onSuccess], [onFailure]): Saves the text set via setPageText() for the page.
* Must be preceded by calling load().
* 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.
*
* prepend([onSuccess], [onFailure]): Adds the text provided via setPrependText() to the start
* of the page. Does not require calling load() first.
*
* move([onSuccess], [onFailure]): Moves a page to another title
*
* deletePage([onSuccess], [onFailure]): Deletes a page (for admins only)
*
* undeletePage([onSuccess], [onFailure]): Undeletes a page (for admins only)
*
* protect([onSuccess], [onFailure]): Protects a page
*
* getPageName(): returns a string containing the name of the loaded page, including the namespace
*
* setPageText(pageText) sets the updated page text that will be saved when save() is called
*
* setAppendText(appendText) sets the text that will be appended to the page when append() is called
*
* setPrependText(prependText) sets the text that will be prepended to the page when prepend() is called
*
* 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
*
* exists(): returns true if the page existed on the wiki when it was last loaded
*
* getCurrentID(): returns a string containing the current revision ID of the page
*
* lookupCreation(onSuccess): Retrieves the username and timestamp of page creation
* onSuccess - callback function which is called when the username and timestamp
* are found within the callback.
* The username can be retrieved using the getCreator() function;
* the timestamp can be retrieved using the getCreationTimestamp() function
*
* getCreator(): returns the user who created the page following lookupCreation()
*
* getCreationTimestamp(): returns an ISOString timestamp of page creation following lookupCreation()
*

* It should be an array of page names (strings).
*
* setOption(optionName, optionValue): Sets a known option:
* - chunkSize (integer): the size of chunks to break the array into (default 50).
* Setting this to a small value (<5) can cause problems.
* - preserveIndividualStatusLines (boolean): keep each page's status element visible
* when worker is complete? See note below
*
* run(worker): Runs the given callback for each page in the list.
* The callback must call workerSuccess when succeeding, or workerFailure
* when failing. If using Morebits.wiki.api or Morebits.wiki.page, this is easily
* done by passing these two functions as parameters to the methods on those
* objects, for instance, page.save(batchOp.workerSuccess, batchOp.workerFailure).
* Make sure the methods are called directly if special success/failure cases arise.
* If you omit to call these methods, the batch operation will stall after the first
* chunk! Also ensure that either workerSuccess or workerFailure is called no more
* than once.
*
* If using preserveIndividualStatusLines, you should try to ensure that the
* workerSuccess callback has access to the page title. This is no problem for
* Morebits.wiki.page objects. But when using the API, please set the
