SteelSoftware Official Quarry System 0.9

Fixed the player's connectid and now finds different players so they can
kill each other. It now makes sure that the person that you're killing
is not yourself lel. There is no quarry refresh unless the round is
restarted(which can be done with the commands "endround" and
"startnewround").

Bugs:
Forcing a new round with only one player will cause a stack overflow and
possibly crash the server.
