Added sm_fm
Updated deprecated GuessSDKVersion to GetEngineVersion
Initial commit of config modules
Renamed lgofnoc_addcvar_scaled to lgofnoc_addcvar_tiered, made the tier a lgofnoc cvar for game agnosia (agnosticism?) and versatility (can be used to vary settings according to player number, difficulty level, etc).
Small compile fixes
