/* = Class: New_window_links = __________________________________________________________
	Generic window opening
	Usage:
		*	ALL EXTERNAL LINKS HAVE FUNCTIONALITY APPLIED AUTOMATICALLY
			TO PREVENT THIS ADD THE ATTRIBUTE rel="same-window" TO THE <a>
			- The windows will have menu's etc.
			
		* 	PDF LINKS  HAVE FUNCTIONALITY APPLIED AUTOMATICALLY
			- The window will have NO menu's etc.
			
		*	EXTERNAL LINKS WITH NO MENUS OR DIFFERENT OPTIONS
			- 	Adding rel="new-window" will make the new window open with no
				menus
			-	adding a json string of options will add/overwrite any standard options
				ex.
				rel="new-win[{width:640,height:480,location:'yes'}]"
				
		*	OPEN INTERNAL LINK IN NEW WINDOW
			- add rel="new-win" OR
			- with options rel="new-win[{width:640,height:480,location:'yes'}]"
				BY DEFAULT THERE WILL BE NO MENU BARS ETC. THIS CAN BE FORCED BY ADDING
				CUSTOM OPTION allmenus:'yes'
