Add voice_channel field to user info to track if user is on a voice channel and which one if yes.
Get info and keep it in server_info channel list about voice channels. This might later be used to somehow (imcb_log or nick changes) indicate buddies being in voice channels (specific or in general).
Split this huge prototyping mess in a single lump into separate files. Better do this early then never.
