/*
This is based on Cheesy Peteza's afk kick plugin.

It will *not* kick, but instead simply put a player who is afk into spectator mode.
This is to keep teams even, rather than making room on a full server.
Especially it works if a player was automatically put into a team (on map change or join).

mp_afktime 300      Time a player is allowed to be AFK in seconds before they are kicked. (minimum 30 sec)
         They time is only accumulated while they are alive.
mp_afkminplayers 2   Minimum number of players required to be on the server before the plugin starts kicking.

version history
1.0c  Check for AFK will be done when player joins a team, spawned or not.
1.0d  No longer kick for being AFK. Instead, player is put into spectator mode.
1.0e  Bug fix: removed is_user_alive query, doesn't work well if the player isn't spawned yet.
1.1   If player hasn't spawned, but is in a team other than spectator, he will be put into spec mode *early* (30s).
1.1.1 Bug fix: Resetting afk data when a player is moved to spectator mode.
1.1.2 Fixed detection if a player has spawned.
1.2   Reset AFK on map change.
