Server can now be set to broadcast on local network (every 10s, approximately 20 bytes of data) where client and slave can pick up its existence. This is on by default.
Default ip address is now "[default]", which means for the master that it will listen to all interface and for the clients and slave that they will automatically work out the master's address from its broadcast.

Should be easy to test if people want too, just follow the instructions on wiki
Code is still very much in flux, so I'd like if people would refrain from making changes (send patches directly to me if you must).
The UI side is very crap, it's basically there just to get things testable. See wiki for known bugs.
