Graphical user interface for Click

Hi Brecht, more about your GUI.

Mazu Networks has donated their KernelHandlerProxy element to the main
Click distribution. With some additional hacking, you can have a
ControlSocket element that talks to a *kernel* configuration! For example,
this configuration:

	khp :: KernelHandlerProxy;
	ControlSocket(tcp, 4000, PROXY khp);

Elements now in CVS.

I understand and sympathize with your constraints! I don't believe that
dealing with the output of ControlSocket would be that bad, particularly
since you can just snarf our work on ClickController. But you have already
done the work for CORBA. Maybe it is now our turn :)

Please release whatever you have whenever you'd like.
