Major changes to the networking core of retroshare to introduce the new serialiser.

- Added new serialiser (PQItem -> RsItem), removed old one.
- switched packet sorting from ChanId (array of ids) to PeerId (string)
- introduced cleaner service interface (pqiservice).
- moved p3disc to service interface.
- modified streamers to use the new serialiser.
- moved msg/chat to service interface.
- removed old source code. (supernode / p3loopback).

I've disabled UDP connections / Proxy and Channels for the moment.
The code it still here, but is not compiled. The Proxy and Channels 
will become services, and the UDP connections will be reworked 
in the near future.
