 * Scroller plugin
 * (c)Eftimie Andrei 2008
 * k3liutZu@gmail.com
 * 
 * You can call it like
 * $('#scroll').listScroll(speed, handlerPrevious, handlerNext);
 * 
 * It should be chainable
 * 
 * It expects html the like
 *	<div id="scroll">
 * 		<ul>
 * 			<li>...</li>
 * 			...
 * 		</ul>
 * 	</div>
 * 
 * Layout should be addressed by CSS
 * list elements should float
