Merged branch v0.5-GenericTunneling into trunk (Rev. 6284 to 6410).

- adds turtle router as a generic tunneling service
- made ftServer a client of the service. Now turtle file items are handled in ftServer
- added new client: p3MsgService to send/recv pgp-encrypted distant messages
- added new client: p3ChatService to perform private (AES-encrypted) distant chat through tunnels.
- The GUI is disabled for now, since it needs some polishing before being fully usable.
