File Cleanup

- Made lighting flatter for visibility (de-linked skybox from light_environment values)
- Made white texture on ramps less reflective to not make them blindingly bright
- Sealed the level with a inverted skybox
- Clipped the skybox boundary so players cant fall out of the map
- Added Weapons that you can pickup without crashing
- Adjusted Boosters to feel like CSGO (as close as possible - it will not be perfect)
- Adjusted teleports to behave like CSGO - maintaining player velocity and angles in relation to the world rather than to Remote destination angles
