Cesspool Alpha 2 Fixed

Apparently Hammer screwed me over and did not save the changes I made to the Alpha 1 version, so here they are, red doors work for real now, sorry y'all.

Since I accidentally shipped this update early in my Alpha 1 Fix, I decided to polish it up and put out the full version here.
I added some cubemaps in places I thought needed them, and I fixed my "little surprise" near the capture point.
Hopefully it all works and you enjoy it immensely.

Fixed red spawn doors not opening (sorry everyone)

Further note: I also realized I accidentally shipped part of the Alpha 2 update I was working on. However, apart from some minor texture errors, there's nothing to be concerned about.
