Handling inactive players

There was an issue that our system occasionally moved players to spectators even though they were active. We fixed the issue as follows.

– If a player finished the entire round without killing anyone, he gets kicked (no ban) at the beginning of the next round.

– You can call !spec playername. The target player will be moved to spectators.

We will not apply a method dependent on the positions of players, as our system is not able to handle these positions in a good manner.
