Cross-game compatibility update

Hey all! Going to keep this brief.

For the latest update, most doors have been temporarily removed until TTT officially supports the global door game object provided by Facepunch. Players from other games who previously had issues opening doors should no longer run into this problem.

Another compatibility improvement is the removal of volumetric fog. The effect was originally intended to provide a subtle atmospheric haze in the foreground, however some rounds would randomly ignore the low density values and crank the fog to full intensity. Certain games also ignored the settings entirely, resulting in an extremely thick mist lingering around the center of the map.

This has now been removed, bringing with it a small performance improvement as a bonus. 

Outside of this, reflections have been improved across many surfaces, the sense of scale and depth has been enhanced, and the construction site scaffolding has been updated (Don't worry I'm also working on that purple doorframe texture).
