Updated protobuf and netty.
Partially implemented client identity and authentication.
A server certificate is generated for the user on first run of Terasology.
When a client joins a server for the first time, they are provided an identity for use on that server.
Disabled compression temporarily (need to work out a bug causing some data to be lost)
Implemented the second half of the authentication process - authenticating with a previously provided certificate.
Added timestamps to the handshake messages.
