Some Integration.

[<miguel nuclecu unam mx>]

Now that we live in a wonderful ORBit world, it would probably be a
good idea to integrate a thing or two:

     - GTCD and the CD player applet.
     - GMix and the panel mixer.

GTCD and GMix should be modified to include the applet functionality
(trivialish, probably move some code) and then make those big
applications register a widget with the panel when they run.

That has always been possible with the corba setup, we just did never
advertised it, as we depended on mico before.

Miguel.
