Big Boxing Station

- Revamped lighting. I added some cool looking stuff in the compiler like radiosity and ambient occlusion.
Lighting was changed so it could work well with those.
- Added more ammuniton packs and medkits.
- Elevator in big boxing area was changed, no it starts from the upper "floor" and goes down. Previously it was the opposite.
- Elevator now has 2 buttons in upper and bottom "floor"s
- Boxes next to elevator were moved to prevent getting stuck.
- There are probably more changes i made that i forgot to mention here.
