Allow sending commands to the server

[errietta]

AFAIK (at least from trying) there's no way for the user to execute commands; I tried /join #channel and it just sent a message. Messages starting with '/' should be sent to the server

yeah, these have to implemented in the client. You don't get them for free by sending them as raw messages to the server.

One could start with a command that allows to send something raw to the server. Most clients support this as /raw and /quote. Users who know IRC well enough can transform typical commands into IRC protocol commands, e.g. /join #foo into /quote JOIN foo or /msg freddyb hi into /raw PRIVMSG freddyb :hi
