 jquery.include-2
 @version  2.0
 @author   John Hunter on 2008-09-20.
 Licence CC-BSD <http://creativecommons.org/licenses/BSD/>

 Uses a standard tag with an src value <span src=""></span> - these are stripped from the dom after loading.
 Can handle nested includes - linking paths in the include file are modifed to match the host page context.
 For post-include scripts $(document).includeReady works the same as $(document).ready

 Based on ideas from hinclude by Mark Nottingham <mnot@pobox.com>
