- Added Martin Howe's morph system update.

- Added support for defining composite textures in HIRESTEX. It is not fully tested
  and right now can't do much more than the old TEXTUREx method.
- Added a few NULL pointer checks to the texture code.
- Made duplicate class names in DECORATE non-fatal. There is really no stability
  concern here and the worst that can happen is that the wrong actor is spawned.
  This was a constant hassle when testing with WADs that contain duplicate resources.
