Added AFK system:
You can set time in seconds after player became afk when he is not moving.
You can set time to kick afk player after some time.
Added new command /afk - Players can tell other players when they are afk (by default there is 30 sec cooldown for this command to prevent spam), you can also disable this command and leve only auto afk system.
Teleport system has been rewrited (it might contain bugs but i didn't find any).
Now when admin mute/unmute someone message will be displayed to all players.
