 *	This script applies dropdown menu capabilities to the default Joomla! 1.5 List style menu module.
 *	This script cleans and re-classes the menu lists similar to the following example:
 *	<ul class="level0">
 *		<li class="active first">
 *			<a>Link</a>
 *			<ul class="level1">
 *				<li class="first last">
 *					<a>link</a>
 *				</li>
 *			</ul>
 *		</li>
 *		<li class="last">
  *			<a>Link</a>
 *			<ul class="level1">
 *				<li class="first last">
 *					<a>Link</a>
 *					<ul class="level2">
 *						<li class="first">
 *							<a>Link</a>
 *						</li>
  *						<li class="last">
 *							<a>Link</a>
 *						</li>
 *					</ul>
 *			</ul>
 *		</li>
