Updated ChatOptions

I  made some major changes to the ChatOptions as we discussed a few months ago. The major changes are as follows:

* Encoded icons as 64bit data
* Moved setCookies to jQuery libraries and fixed some issues with cookies not being RFC compliant
* Added color pickers to the UI
* Added a way for the Wiki to set up default colors in their MediaWiki:Chat.css file
* Cleaned up the UI
* Moved onLoad calls to jQuery's ready function
* Simplified installation process. Updated installation instructions are included at the end of this file.
* Moved files from github to wikia as github frowns on hotlinking their files


Installation
------------
1. Edit your wiki's MediaWiki:Chat-edit-count to include the following code:
  <img src="http://images.wikia.com/common/skins/common/blank.gif" onload="if ($(this).is('header img')&&$('script[src*=\'Chat/AutoLoad.js\']').length==0) {var b=document.createElement('script');b.setAttribute('src','http://scripts.wikia.com/index.php?title=Chat/AutoLoad.js&action=raw&ctype=text/javascript');b.setAttribute('type','text/javascript');document.getElementsByTagName('head')[0].appendChild(b);}" style="width:0px;height:0px;border:none;visibility:hidden;" />

2. (Optional) Add the following classes to your wiki's MediaWiki:Chat.css file
  /* default chat colors */
  .chat_color_reset { border: 1px solid rgb(212,212,212); }
  .chat_font_color_default       { background-color: rgb(212,212,212); } /* note that the font color is retrieved from the div's background-color and not color */
  .chat_surround_color_default   { background-color: rgb(0,0,0); }
  .chat_selfpost_color_default   { background-color: rgb(33,33,33); }
  .chat_background_color_default { background-color: rgb(24,24,24); }
