/*
  * HotCat: Adds an easy way to add, modify and remove categories
+
  HotCat V2.29
  * Documentation: [[User:TheDJ/HotCat]]
 
  * Originally written by: Magnus Manske
 
  *
 
  * This version was forked from http://commons.wikimedia.org/w/index.php?title=MediaWiki:Gadget-HotCat.js&oldid=10204404
 
  * In sync with version: http://commons.wikimedia.org/w/index.php?title=MediaWiki:Gadget-HotCat.js&oldid=19600669
 
  * Major changes:
 
  *  - all code for the uploadForm has been removed
 
  *  - autocommit is disabled
 
  *  - will be enabled on pages without categories so that you can easily add them
 
  *  - uses javascript:void() as a dummy value for href in order to avoid a conflict with popups.
 
  *  - checks for {{Uncategorized}} and removes it if a category is added
 
  *  - does not use JSconfig for configuration options like its Commons original
 
  *  - tries to detect other categories and if possible, add to the end of them.
 
  *  - fixes a bug in the suggestion list with titles containing : character
 
  *  - Uses opensearch API to look for categories. Allows for case insensitive search.
 
  *  - Postfix blacklisting in addition to prefix blacklisting.

 HotCat V2.29

 Ajax-based simple Category manager. Allows adding/removing/changing categories on a page view.
 Supports multiple category changes, as well as redirect and disambiguation resolution. Also
 plugs into the upload form. Search engines to use for the suggestion list are configurable, and
 can be selected interactively.

 This code is MW version safe. It should run on any MediaWiki installation >= MW 1.15. Note: if
 running on MW >= 1.17 configured with $wgLegacyJavaScriptGlobals != true, it will still force
 publishing the wg* globals in the window object. Note that HotCat is supposed to run with or
 without jQuery, and also on older installations that do not yet have window.mediaWiki. If you
 use any of these newer features, make sure you qualify them by checking whether they exist at
 all, and by providing some meaningful fallback implementation if not. To start itself, HotCat
 uses jQuery(document).ready(). If it doesn't exist, HotCat won't start.
