Moved Chunk.Block to its own class in the actors package. Updated import statements and structdef.txt. Issue with LibStruct where enum instance variables cannot be structs as they are accessed through intermediary method "access$000", which cannot be annotated as it is generated at compile time. GLUtils.FrustumCulling.Plane had a member Vector4 but now FrustumCulling owns the Vector4 instances....which makes more sense. Completely redid how the BulletRenderer sorts the Bullet as struct types cannot be used in collections.
