Cishet a3

- Added an actual skybox. In prior versions, a "diaper skybox" cube around the map was used instead.
- Remade BLU spawn
--- Moved Tom Cruise to a less obvious spot
--- Made the lightbulb wire in BLU spawn less thick
- Remade RED spawn
--- Reworked the shack in the former "upper level" detail area, which is now connected to RED spawn.
--- Removed clipping from the inaccessable bastion ledge next to spawn and added a staircase to it
- Other minor layout and detail revisions around the point

- Removed stickybombs from the weapon whitelist for being overpowered
- Removed the Shotstop from the whitelist. This was a bug, and was intended to be blacklisted in the first place
- Added an ammopack to an empty spot in front of the bastion
- Added some cover in front of RED spawn
- Raised BLU spawn's walls by 64hu to help combat spawncamping
- Clipped the resupply cabinets in attempt to fix a rare bug where using them would kill you (Damn you, Source engine!)
- Added a single cubemap

This update was made before the imp today. As of writing, the server just switch off of my map, and certain... revelations were made clear to me. I'll start on a hotflix right away.
