    /* a problem arises if a server splits, services (Q) get restarted during the split,
       and they join a (now) empty channel (because of the split). the TS on our link will be
       younger then the ts on the rejoining server, so we lose our modes.
       Possible solutions:
       a) if this happens, the B line will have a mode string, so we can find the channels that way,
          we parse the users/modes, and rejoin the channel.
       b) we save the timestamps of known channels, and if we get one that doesn't equal ours, we
          parse it like p10 discribes.
       c) we trust services not to get restarted during splits ;p

       a would be the simple dirty solution, b would require more work, and slow us down a bit more
       but be correct


       We're going for a.

       another problem surfaced where the timestamp being burst was a 0 or a 1. I have no idea why, however
       this causes deops aswell. another fix was put inplace.
