[XForms] Adding more calls to support fl_register_client_callback()?

[Jeff]

I'll put together a quicky threaded app later today when I get a chance.
It will just be a clock. The form will display the time while the thread 
will do the actual time functions and send the time for display via a 
client message. That ok?
