Support raw IRC messages

Messages received on an IRC server JID are forwarded as raw IRC messages.

“Gateway shutdown” quit message, except that biboumi does not exit when
using this ad-hoc command.
### Raw IRC messages
Biboumi tries to support as many IRC features as possible, but doesn’t
handle everything yet (or ever). In order to let the user send any
arbitrary IRC message, biboumi forwards any XMPP message received on an IRC
Server JID (see *ADDRESSING*) as a raw command to that IRC server.
For example, to WHOIS the user Foo on the server irc.example.com, a user can
send the message “WHOIS Foo” to “irc.example.com@biboumi.example.com”.
The message will be forwarded as is, without any modification appart from
adding "\r\n" at the end (to make it a valid IRC message). You need to have
a little bit of understanding of the IRC protocol to use this feature.
