Fixed bugbait crashing in a certain scenario
Prevent invalid VTF file flags from crashing the game
For TEXTUREFLAGS_RENDERTARGET / TEXTUREFLAGS_DEPTHRENDERTARGET flags, instead of refusing to load these files, simply remove the flag so we don't crash later on. These flags are invalid to be in files.
Move ANISOTROPIC stuff from DImage to notification lib
Added SENT_AI:ResolveCustomFlyCollision( trace, vecVel )
Fix player NPC squad HUD not having a background
* Also make the HUD element fit all NPCs following you (up to 16 right now)
Delete some unused CGarrysMod stuff
* Also block building_cubemaps convar (can still read it)
* Removes IGarrysMod::MD5String, PlaySound, GetMapName
* Removes CGarrysMod::SteamLogon, UpdateVGUI, MD5String, PlaySound, LoadDLLModule, GetMapName, GetServerAddress, m_ServerAddress, IsSteamOverlayActive, OnGameOverlayActivated
Bump renderData to 16MB max
* Was 4.4 MB. This is a bandaid fix for many skinned meshes existing on screen at once causing crashes (on x86-64)
