Gameplay Mod TopDownQuake

I completely blanked on posting the 2.1 version on Slipseer over a year ago. Sorry about that.

Completely rewritten from the ground up. Still relies exclusively on the FTEQW sourceport, sadly. Still missing a few features, but overall should be a much cleaner and stronger experience.

- Renamed to "Automap Quake"
- Removed second topdown mode (sorry, might add it back later)
- Added toggle command
- Added +showscores keybind, for DOOM-like automap
- Added experimental minimap
- Automap is now on by default
- Added automap_activate console command (not cvar) to turn on automap mode
- Added +automap keybind, if you don't want to use +showscores
- Added automap_scale to change how much of the world you can see
- Added fog of war mode
- Made it so you can see areas that aren't on your immediate height level
- All automap cvars are saved to the config
