/*

	addLoadEvent.js
		Replaces userAction.js in delay loading scripts.  Executes scripts at window.load in order of priority with lowest number executed first.  Defaults to a priority of 3 if none passed.
	Usage:
		Enclose the function you wish to call in function(){} and add a priority (if different from 3) to call the function.
	Priorities:
		Priorities should be a value between 1-5 inclusive, the lowest being highest priority.  Examples of high prorities would be lazy image loading (1).  Low priorities would be intellitxt(4), addthis (5), facebooklike (5).  A value of 3 is considered average and loaded by default.
	Examples:
		addLoadEvent(function(){coolstuff();}, 3);
		addLoadEvent(function(){
			$('.featuredItems').onVisible({callback: function() {
				$('.featuredItemImage img',this).lazyImage();
			}});
		}, 1);
		
		onVisible() will be executed first before coolstuff()
		
		addLoadEvent also accepts $.getScript and callback functions -
		
		addLoadEvent(
			'script.js',
			function(){alert("script.js loaded!");},
			1
		);
