black_mesa B5

There was a wall blocking BLU's way to the computer room so I moved it.

After some careful thinking, I decided to add another hallway to ensure that there would be a way of escape in case of spawn camping.

Note: the cubemaps may not be 100% accurate due to the changes I made, but right now my main concern is the traffic flow.

See overview for more details.

Just forgot to name it koth_black_mesa_b4

that's all. It's named right now.
