For Issue #1 - /brb command (named to avoid colliding with existing /afk cmd,
which only goes afk): posts emote message and chat-log, sets status to AFK,
leaves after next track. Up next: save off autowoot status and restore
on return.
Merge remote-tracking branch 'upstream/master'
Issue #1: /brb command, which is /afk plus:
 - turn off autowoot, save current autowoot status for restore
 - post emote to chat log
 - do a /leaveafter
Merge pull request #13 from benetd/master
