Returns if the mod running on the server supports colored menus.
The full list of mods supporting colored menus:
Counter-Strike, Counter-Strike: Condition Zero, Deathmatch Classic,
Day of Defeat, Team Fortress Classic and Half-Life: Deathmatch.
Since this is a stock and compiled into the plugin, the list of
supported mods will not update and require recompilation of the plugin
if the list ever changed.
1 if colored menus are supported, 0 otherwise
