Changed DecalSet to use raw binary buffer serialization for the decal data for more size-optimal and faster load/save.
Fixed animation glitches on models with decals caused by incorrect access to bone positions from multiple threads. This was caused by an earlier bugfix (NinjaSnowWar bodies hanging in midair) which was now fixed instead by setting a nonzero invisible animation LOD factor for the ninjas.
Code cleanup.
