Renamed, and removed some things as a result of refactoring.

Done a whole bunch of stuff: ...

- Added service discovery.
 - Refactored the IMapPanel interface and LabelProcessor to make panels simpler.
 - Numbers now end up in queue label.

Nearly finished.  Need to do testing in labs.

Made the server threads deamon threads. No real need too but it is the correct thing to do.

Initial commit.
