Fixed the third map, but I am unable to fix the second map due to me breaking its lighting in the process while converting its .vcd file back to the .bsp file in Hammer, something that is way beyond my knowledge to fix it. About the third map, besides fixing the spawn points, I somehow fixed the cubemap issue, although parts of the staircase near the beginning of the third map are now dark. However, that map should run smoothly now.

Fixed the spawn points for the first map.

Initial addon creation.
