fixed my last few lighting problems

Fixed a few lighting problems, added rockets and snipers to bases, and replaced central rocket with scattershot.

After looking over the map I found a few objects outside the map that I had accidentally placed that were not visible in the map and were worthless to the map. Deleting these objects freed up object space so now i was finally able to place the flags needed for ctf.

Added some trees and terrain in the background, fixed a few spawning issues and lighting issues. Also I added an underwater effect in the deeper spots of the lake so when you go underwater it actually looks like you are underwater. And I made some slight texture adjustments to the forerunner structure.
