Allow custom maps without requiring mods

[PureTryOut]

This has been a bane in my existance since I started hosting servers.

Currently, if you want to run any custom map, Cod4 requires you to specify a mod, even if it's not wanted. Since I want the stock Cod4 gameplay but with custom maps like ports from MW2 and other games, this is really annoying.

Currently I specify an empty mod folder, and set ModStats to 0 and sv_showasranked to 1. When a player joins, it still looks like the player is starting a mod, as it shows something like mod played: myemptymodfolder on the load screen.

Could (I guess using the client-side Cod4X) an option be added to play custom maps without loading a mod?
