- Made all the basic texture classes local to their implementation.

They are not needed anywhere else.
- Changed the HackHack hack for corrupt 256 pixel high textures that
  FMultiPatchTexture only calls a virtual function instead of doing any
  type checks of the patch itself.
- Cleaned up the constant definitions in doomdata.h.
- Moved the TEXTUREx structures from doomdata.h to multipatchtexture.cpp
  because they are used only in this one file.
- Removed some more typedefs from r_defs.h and doomdata.h
- Moved local polyobject data definitions from p_local.h to po_man.cpp.
