MAP39: Update & Issues

[Rex Claussen]

A. UPDATE:
1. MAP39 is the sixteenth map of the "expansion pack", and the seventh in the "Deimos" episode. It uses Half-Life enemies and textures but DooM weapons. Also, the maps in this episode use GZDooM features somewhat liberally.
2. This map is a built from scratch and is meant to represent an alien space station
3. Progression: Use the low-gravity tubes to move from one level to the next
4. Mapping = 100% complete
5. Gameplay = 0% complete

B. ISSUES:
1. As explained in this thread, there is not yet functionality to see how much DooM weapon ammo is being carried
