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.
