Bag Listener Test Patch

[Mike Kestner <mkestner enteract com>]

I'm attaching a patch to the sample-control-container that fixes a
couple of UIH compat bugs and adds some listener sample code for
PropertyBag listeners.  

It adds a button that pauses and resumes the clock control and a
listener on the clock's "running" property that updates it's status in
the CList.

Let me know if I can commit.

Mike
