Fixes #173.  Remove recursive calls in eventInMenu, descendantOf and findElement to avoid stack overflow errors when closing menus from a mouse click in deeply nested HTML structures.  This fix will be bundled in jxlib beta 5 which needs to be released in sync with changes to the mapguide templates (for fusion) so I have manually applied the fixes to this version of jxlib for now.
