Chat system

[Chris Armstrong]

Okay, noted. Only thing is that the chat module itself shouldn't (well, wasn't
planned) to have anything to do with sockets. inetd handles connections
and just starts my game, and the chat system is just a plugin to my game..
Although I guess I could still use the select thing.. Maybe with named pipes?
(I don't know much about those.)
or maybe I'll just set up a socket server for the chat module that only gets
local connections, although I really don't want to do this.
