YES! We finally have dynamic signals between Core and Client, meaning that arbitrary
signals and slots can be attached to the SignalProxy, rather than having hard-coded
stuff in the old CoreProxy and ClientProxy classes. This was made possible by integrating
QxtRPCPeer from the guys at <http://www.libqxt.org>.

Everything should work now as before, except connections to an internal core, which are disabled
for the moment. The connection handling had to be completely rewritten, and I still need a QIODevice
that can do loopback connections.

The code is still a big mess, I am deliberately committing this before clean-up, in case I
delete something we still need. Expect a much cleaner version soon.

Oh, and VarMap has been substituted by QVariantMap project-wide. We cannot send VarMap through the
SignalProxy, and I decided to change the naming consistently everywhere.
