Irrigation a5

-Added a larger open door to the defending platform outside B, with staircases with easy access in and out of the control-point room. (This should make it easier to built engineer nests).
-Made C (mid) slightly narrower (128hu on each side) to give people more cover and make the map a little less open. (Its also easier for engineers to build sentries here too!)
-Changed pickup placement around B. There is now a higher risk-reward tradeoff with full health and ammo packs in the sewers.
-Lighting is a bit improved.
-Displacements are a bit improved.
-Added white stripes to the edges of perch-points to make them more visible.
-Did some minor optimization with areaportals.
-Made the sniper rooms brighter so you can see who's shooting at you.

I revived this 3-year-old bad map, and reworked a lot of the layout around control point B to streamline it and make it simpler. The sewers actually lead to somewhere useful now, and I simplified tons of useless rooms and removed a lot of doorways.

Hopefully there are some positive gameplay changes instead of it just looking nicer.
