sourcemod/tools/gdc-psyfork/GameConfigs.cpp
Nicholas Hastings b7ac61cbea Updated gdc-psyfork with current (NPOTB). 
- Added script support for Steam3 content (CS:GO, ND, etc.).
- Removed script steam.inf temp-move hack now that DepotDownloader correctly handles checksums.
- Updated symbols.txt.
- Fixed gdc having issues with gamedata files that contain new or unknown sections ("Addresses").
