Alibek Omarov	1ee2186f72	filesystem: massively rework how scanning game directories work * No more conversion from liblist.gam to gameinfo.txt. We are using liblist.gam directly now. gameinfo.txt being native format to Xash3D not only remains, it takes priority over liblist.gam. * Quake game directories now don't receive autogenerated gameinfo.txt. * Empty directories don't get gameinfo.txt either, finally making it easier to support HD addon folders. * If user still wishes to generate gameinfo.txt, there is now command fs_make_gameinfo that creates gameinfo.txt for currently running game. * No more creating empty folders for RoDir. They are now created on demand.	2025-01-07 10:10:18 +03:00
