GameData (.fgd) is now managed, game entities are now loaded at runtime from their type information instead of from .fgd files. This also runs both ways and let's us access all GameData from C#. * Packages you use in your map get saved ( e.g facepunch.dm98, valve.cstrike ) and fetched on map load * Map compiler doesn't try to load fgds anymore, replace it with a KV3 provided by Hammer -> ResourceCompiler. * Map classes can be loaded directly from a LocalAddon or a RemoteP * Remove .fgds of anything that is a managed entity, also remove legacy syntax so we can remove shit loads of code. * Obsolete [Spawnflags] they're confusing for everyone, use a properly named enum with [Flags] on instead. ( Enums with [Flags] also work now, no more FGDType("bitflags") required. If fgd files fail to load, don't fuck managed game data for it.
