 * Originally written by Simon Willison (http://simonwillison.net/2004/May/26/addLoadEvent/)
 * Incorporated with code by Dean Edwards (http://dean.edwards.name/weblog/2006/06/again)
 * Takes a function as an argument which should be executed once the DOM has loaded
 * Parameters: function func
 * Example:
 *		addLoadEvent(myFunction);
 *		addLoadEvent(function() {
 *			alert ('a');
 *		});
