	This plugin registers flXHR with the new jQuery XHR registry, so it can be chosen as a custom transport
	for Ajax communication. flXHR will work as a replacement of the native XHR, additionally allowing
	authorized cross-domain communication through flash's crossdomain.xml policy model.
	
	This plugin allows an author to register a set of flXHR configuration options to be tied to each URL
	that will be communicated with. Typical usage might be:
	
	jQuery.ajaxSetup({transport:'flXHRproxy'});
	jQuery.flXHRproxy.registerOptions('http://www.mydomain.com/',{xmlResponseText:false...});
	jQuery.flXHRproxy.registerOptions('http://rss.mydomain.com/',{xmlResponseText:true...});
	...
	jQuery.ajax({url:'http://www.mydomain.com/something.html'...});
	...
	jQuery.ajax({url:'http://rss.mydomain.com/feed.html'...});
