Ports: Add Duke Nukem 3D

This adds 'JonoF's Duke Nukem 3D Port'.

Parts of the network-related stuff has been patched out.
See patch: patches/0002-mmulti.c-ifdef-out-network-related-stuff-we-currentl.patch

Notes:
- Some sound work seems to be needed. During the title screen and
  gameplay SFX works, but music does not play. At the ending screen of
  Hollywood Holocaust music does play.
- GTK has been disabled, by default it will start in fullscreen, to get
  back to windowed mode can be done through the Video Settings.
- OpenGL support has been disabled, as far as I can tell it will need
  OpenGL 2.0 support which we do not currently have.
- True 3D renderer has been turned on.
