Subject: [PATCH] (Marticus) -Added documentation and cleaned up the code
 -Created amx_hideslots cvar to replace #define HIDE_RESERVED_SLOTS -Removed
 ackSignal *sigh* and the horribly coded setVisibleSlots function -Removed
 client disconnect -Created global variable gPlayerLimit to be used in both
 functions -Moved set cvar sv_visiblemaxplayers to plugin_init

+* 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.
