 (c) 2008-2009 Aleksander Ovcharenko

 version 1.1

 uses other jquery plugins:
 - jquery.ifixpng.js (for IE6)
 - ui.draggable, ui.core (optional)
 
 example:
 <div id="testdiv" style="background-color:#CCCCCC; width:400px; padding:15px; height:100px;">test</div>
 
<a href="javascript: void(0);" 
onclick="$('#testdiv').jMsgHint('red',
							 'testing message',
							 {
								 lifetime: 0,
								 drag: true
								});"> test </a>
<br />

<a href="javascript: void(0);" 
onclick="$('#testdiv').jMsgHint('green',
								 'All ok!',
								 {lifetime: 2000,
								 drag: false});"> test2 </a>
