        * src/ttt-args.h:
        * src/ttt-args.c: (ttt_args_help), (ttt_args_parse): Add a -u,
        --user option for controlling the uid under which the server
        process runs.

        * src/ttt.h:
        * src/ttt-server.c: (ttt_server_register_client), (main): Recert
        the dup of stdout which wasn't working. Instead just print client
        join information on stderr so that it goes into the log. Implement
        support for the user option by calling setuid to drop root
        privileges the process might start out with.
