	JQuery Externalify 0.2
	by Aaron Lozier (lozieraj-[at]-gmail.com) (Twitter: @ajlozier)
	version 0.2
		* "confirm function" and "before leave" function added
	
	* Binds a click event to all anchor tags passed to it which evaluates whether or not the href is a part of the current domain or not.
	* If it is, returns true and click is treated normally.
	* If not, location is opened in a new window.
	* No options at this time.
	* Wishlist: New window parameters and/or ability to create custom callbacks.
		
	Project Page:	
		* http://informationarchitech.com/externalify/
		
	Dependencies:
		* jQuery 1.2.x
 
	Basic Usage:
	
	$('a').externalify();
