Enhancement - Possibly allowing menu level BSP overrides

[ghost]

I had an idea that I'm going to test out this weekend locally where game_mod will check the mod directory first for a frontend_patch.ff and load that one if provided, then default to the provided one. This could necessarily allow users to build a custom level and add more immersion to their mod. Technically the only problem I see would be replicating the entities required to spawn the player in radiant.

The issue with this is that the menu files in the mod tools are terribly out of date and break numerous features completely when used. The current version of frontend_patch.ff largely used rewritten menu files and custom ignore list overrides to minimize the number of files it includes.

That was the main concern, though the only menus we'd need would basically be a way to launch the map solo, we wouldn't even want a full map list, if the user wants it they simply unload our mod. And a coop menu.
