* PROTOCOL:
* src/ttt-server.c: (ttt_server_init),
(ttt_server_register_client): Remove unique-name generation from
the server. The client is going to have to have code to do this
anyway.
* src/ttt-client.c: Change minimum arguments for HELO from 0 to 1.
* TODO: Note that HELO and ERROR INVALIDNAME are implemented in
the server.
