In this update, I have reapplied the changes in a re-decompiled version of Cobblestone.
It fixes broken geometry and microholes directly and visual glitches with bad performance indirectly.

*KNOWN BUGS*:
- NODRAW optimizations have not been ported over.
- Radar file has not been updated due to TAR visgroups not being carried over.

General:
- Readjusted and reprioritized spawns.
- Fixed cubemaps, occluders and misplaced overlays.
- Fixed broken areaportals and added new ones to outside areas.
- Fixed some overlapping brushes.
- Toilets are no longer accessible.

Bombsite A:
- Shortened back the A Bombsite (matches the last pre-halloween version).
- Moved the tree near the wooden wall to provide better cover.
- Removed a barrel behind the wooden wall.
- Fixed broken geometry and clipping of the heightened wall.
- Added a rock on CT Ramp to provide cover.

Danger:
- Adjusted geometry and sightlines.

Middle:
- Removed top set of scaffolding outside of Middle to make grenade throws easier.
- Made geometry above the rest of scaffolding non-solid to ease grenade throws.
- Closed-off the building on sidewalk.

B Halls:
- Swapped the ugly, added wall in Snake for a platform.
- Tweaked geometry of stairs in both B Halls and Snake.

Drop:
- Swapped ladder for a self-boost with barrels.
- Added a window that gives players ability to jump off on B Long.
- Removed a wooden pillar in the middle of Drop.

Bombsite B:
- Readded the alcove behind the bombsite.
- Extended clipping of railing to make self-boost on tree much easier.
- Made geometry above T-side of B Long non-solid to ease grenade throws.
