Replace body onunload=`GUnload()` with jQuery

If you use Google maps it’s important to use GUnload on the page’s unload event. It’s ok when you can access the body tag directly. But if you have the Google map functionality wrapped inside an ascx you need a different approach.

In fact is very easy to use jQuery to “catch” the unload event. In case anyone else needs it:

$(window).unload( function () { GUnload(); } );
