Add some sanity checks for malformed models that could crash the game (to do w/ textures)
Can now build tier0, tier1, vstdlib and some others for x86-64
Build VPK.exe like x86-64 already does
Delete replay.dll/replay.so which are unused
Update Build-Game.bat
Improve V49 model support for VRAD static props
-allowdynamicpropsasstatic also allows props without $staticprop
VRAD static prop lightmaps respects skins (crash fix as well) + sanity checks for model loading
Fixed an issue with format strings
