// addLoadEvent function as seen at http://simon.incutio.com/archive/2004/05/26/addLoadEvent
// allows you to stack functions and apply them to the onload event and also means you 
// can abstract onload functions from the html
// I've added an argument 'arg' for onload functions with an argument
// Could probably be better implemented with 'arguments[]'
