/*** @title: Favicons  @version: 2.0  @author: Andreas Lagerkvist  @date: 2008-09-16  @url: http://andreaslagerkvist.com/jquery/favicons/  @license: http://creativecommons.org/licenses/by/3.0/  @copyright: 2008 Andreas Lagerkvist (andreaslagerkvist.com)  @requires: jquery  @does: This little plug-in will insert favicons to all external links found on your site. The plug-in scans the URL the link is pointing to for a favicon and, if it can't find one, displays any generic favicon-image you like instead.  @howto: jQuery(document.body).favicons({insert: 'prependTo'}); would prepend favicons to every external link in the document.  You wanna run the plug-in on a parent-element of the external links. Unless you want certain external links _not_ to have a favicon there's no reason not to run the plug-in on document.body.  @exampleHTML: <ul> <li><a href="http://www.codinghorror.com/blog/">Coding Horror</a></li> <li><a href="http://remysharp.com">remy sharp's b:log</a></li> <li><a href="http://snook.ca/jonathan/">Snook.ca</a></li> <li><a href="http://www.danwebb.net">DanWebb.net</a></li> <li><a href="http://www.dustindiaz.com/">DustinDiaz.com</a></li> </ul>  @exampleJS: jQuery('#jquery-favicons-example').favicons({insert: 'insertBefore', defaultIco: WEBROOT +'aFramework/Styles/__common/gfx/jquery.favicons.png'}); ***/
