Dynatrack.cs: Dynatrack now creates a ShapePrimitive and uses SceneryMaterial. All track profile material parameters are now aligned with SceneryMaterial member variables. Both STF and XML forms of file formats for defining track profiles are temporarily withdrawn. A default profile is built from code. The number of textures referenced in a track profile is no longer limited.
Shapes.cs: Added a new SFile-less constructor for VertexBufferSet.
Materials.cs: All DynatrackMaterial code has been marked (commented) for future deletion.
Common\Helpers.cs: public static int EncodeMaterialOptions(LODItem lod) added to encode SceneryMaterial option codes.
