  * HotCat: Adds an easy way to add, modify and remove categories 
  * 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
  * Major changes:
  *   - blacklist code is disabled.
  *   - 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.
