	Version 0.8
	TODO:
	Test in ALL the following IE7+, FF3+, Safari 3.2+, Chrome when it hits version 1.0
	Add option: add Class to show states :default or :usertext
	Add option: specify class names for default and user text
	fix: select bug. If you focus, blur, focus, that last focus will not work with select()?
	
	Example default useage;
	$('input[type=text]').dynoBox();
	
	Example to add text inside the input from a label:
	$('input[type=text]').dynoBox({addFromLabel:'#header label'});
