	JavaScript List Markers

	===================================================================
	
	Adds XHTML invalid attributes "start" and "value".
	Bases on classes. For example:
		<ol class="start:100"> becomes <ol class="start:100" start="100">
		<li class="value:-1"> becomes <li class="value:-1" value="1">
		
	Why? Because browsers don't support advanced CSS (generated 
	content with complex styling) and sometimes we need to show 
	our boss 100% validated site.

		* Safari - it seems to ignore "start" attribute added by JS
