Hopefully it sucks less

-redid the area around the control point
-expanded the the rooms a little bit
-redid the spawnrooms
-added clipping so players can no longer jump on the building's roof
-probably some other stuff I don't remember

Despite not ever being tested I'm still moving this to a2

-Fixed multiple edges players could get caught on
-actually made the dang cubemaps
-upped a small healthpack to a medium
-changed the roof designs
