* Notes:
* sv_visiblemaxplayers is a steam cvar which hides given number of slots
* from clients. This is only useful to those who wish to have hidden reserved
* slots. With 1 reserved slot, max players 17, this cvar can be used to make
* the server appear to have only 16 available slots. The client can use the gui
* to "auto join" when a slot is available. Players who know they have access
* to that reserved slot can connect using the console command "connect".
*
* This plugin was designed to check players with reservation slots and kick
* those who do not have one. With the revised hidden slot feature, all other
* players can use their client's very useful auto join feature.
