Event-based tests

[James Margaris <jm...@nexaweb.com>]

I am adding a new section to the widgets test index.html page for event
testing. I changed reportEvent() in the test class to write to div
instead of put up an alert, so it should be much easier and smoother to
test events. freePanelEvents.xal is a an example of basic event testing.
I am trying to get the basic events like onMouseDown working for
everything, as well as some more attributes like "focused"
