	Function search at Fx.CSS.js can't find styles from files which imported by @import. So this fix that bug.

	It can enabled style which css files added by @import.

	It is usefull for recursively imported css files with @import.
	
	With that patch u can use morph like effects on style files imported by @import. 
	
	Tested on Internet Explorer 6 and 7, Mozilla Firefox 3.0 and Safari 3.
	
	Using:
		<script type="text/javascript" src="./mootools.js"></script>
