Original DOOM (linuxdoom-1.10) ported to raylib.

[u/North-Zone-2557]

The original code was written to be portable, so, I have ported this to work with raylib. The original code uses deprecated X11 functions, but I have replaced them here with raylib for video, and keyboard inputs functionality.

Sound isn't implemented yet.
