* Facebox (for jQuery)
* version: 1.2 (03/13/2008)
* @requires jQuery v1.2 or later
*
* Examples at http://famspam.com/facebox/
* Code at http://github.com/defunkt/facebox

* Copyright 2007, 2008 Chris Wanstrath [ chris@ozmm.org ]
*
* Usage:
*
* jQuery(document).ready(function() {
* jQuery('a[rel*=facebox]').facebox()
* })
*
* <a href="#terms" rel="facebox">Terms</a>
* Loads the #terms div in the box
*
* <a href="terms.html" rel="facebox">Terms</a>
* Loads the terms.html page in the box
*
* <a href="terms.png" rel="facebox">Terms</a>
* Loads the terms.png image in the box
*
*
* You can also use it programmatically:
*
* jQuery.facebox('some html')
*
* This will open a facebox with "some html" as the content.
*
* jQuery.facebox(function() { ajaxes })
*
* This will show a loading screen before the passed function is called,
* allowing for a better ajax experience.
*
* Want to close the facebox? Trigger the 'close.facebox' document event:
*
* jQuery(document).trigger('close.facebox')
*
