//		I.e. They do not mangle the href attribute of the 'a' element	//
//		They also degrade well when javascript is off and will behave	//
//		like standard popups.											//
//																		//
//		Usuage:															//
//			<a href="www.google.co.nz" target="_blank" 					//
//				onClick="avant.popupLib.link_popup(this); 				//
//							return false;">CLICK ME</a>					//
//																		//
//		The functions can also be used on elements other than links		//
//		<input onClick="raw_popup('www.google.co.nz'); return false;"	//
//																		//
//		Popup Features:													//
//			Both link_popup and raw_popup can be passed a features 		//
//			string. This is the standard html popup string. When		//
//			no custom features are passed the default (_POPUP_FEATURES)	//
//			will be used.												//
