From bf7b05ef72bbdac97704d262ddfe418908267535 Mon Sep 17 00:00:00 2001

Subject: Implement the Bridge class to translate between the two protocols
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add all useful classes as well: Jid, Iid, IrcChannel, IrcUser etc to
properly keep the informations about what we receive from the IRC server.

Only handle the MUC join stanza, and send the list of users in the IRC
channel to the XMPP user, and the IRC channel’s topic, for now.
