Updated GWT-Stuff release

[Sandy McArthur]

I've packaged up a new GWT-Stuff release now online at
http://code.google.com/p/gwt-stuff/

The sources were at a good point to be cleaned up for a release. I'd
still consider them beta but thanks to the help of Jon Wells and
Adrian Bosworth there are some release worthy improvments. Jon's
feedback has helped improve the EventList module quite a bit. Adrian
asked the right questions and provided a patch that lead to the
AttachRenderer interface and a 150% to 300% performance improvement on
events propagation depending on the browser.

If you have been creating event listeners that update rows styles or
appearance in ObjectListTable.Renderer's render method you need to use
AttachRenderer's onAttach and onDetach methods to add and remove event
listeners as rows are added and removed. If you don't remove event
listeners when onDetach is called you'll likely create a memory leak.

I accidentally included unit test classes and other non-production
classes in the GWT-Stuff-20070227.jar . If your IDE auto-completes the
presence of those classes may be clutter you don't want. I've just
posted GWT-Stuff-20070228.jar which is the same except without the
test classes. No need to upgrade if those files don't bother you.
