All lump structures store their source data as a byte array now, so even unknown parts of structures are stored when they were discarded before. This means lumps can be read and written without losing any information. New extension methods for Vector2d, 3d and 4d, Vertex, Plane and Color to get their components as bytes for easy storage. Add support for most Call of Duty 2 structures. There's still some missing.
