Big update :). This is intended to optimize the map a bit to get framerates a little more stable. I've also completely overhauled lighting in several areas and added/removed/shuffled around various details in the process of doing that.

There was a certain area in the main lobby room where my FPS would drop to ~135-140 from its usual ~185-190 in the map editor. That area now drops to ~185-190 fps while every other area stays around 200+. It'll probably run a bit worse in actual SDNL but FPS should be noticeably more stable at least.

Gameplay Changes - Pickups, Gametypes
- Map layout now changes in all team-based modes. Both teams spawn on opposite sides of the lobby room, which is split in half with shutter doors. The central brain room is blocked off, giving the map a U-shaped, vaguely almost symmetrical-like (but not really) layout
- Rearranged weapon and armor pickups so that each side of the map has more-or-less the same variety of pickups
- Removed all previous super weapon pickups. There are now two super weapon pickups in the central brain room

Gameplay Changes - Physics Props, Grav Glove
- Replaced crates with their breakable versions
- Replaced all barrels with their physics variants, replaced all crates with their destructible variants
- Physics objects now reset and respawn during round intermissions
- Added several more destructible crates around the map (especially in the lobby)

Gameplay Changes - Miscellaneous
- Lobby: Lighting is a lot moodier now; the ceiling is now almost pitch black, so any vantage points up there have been blocked off (sorry). You can still stand on the big brain though
- Lobby: Added LED light displays on some walls
- Surveillance: Replaced ladders with launch pads

Visual Changes
- General: Retextured many areas
- Lobby / Surveillance: Lighting is significantly darker, with more extreme colors and contrasts
- Lobby: Added some screen walls, replaced ceiling light fixtures, replaced flowers in the planters below the busts, removed the out-of-bounds entrance room
- Surveillance: Replaced desks, added another big screen in the center, replaced the giant central processor/battery and made it spin
- Freezer: Remodeled brain vats and wall pipes, replaced some crate pallets with processing tanks
- Central Room: Updated textures for the catwalks, slightly adjusted lighting, updated wall textures, remade connecting corridors

Fixes
- Fixed several broken spawn points (they might've only broke while working on this update. Regardless they should all be working now)
- Fixed countless weird and wacky lighting issues with sloped walls and surfaces

Optimizations
- Removed ~1,700 items by simplifying various props (such as the brain vats in the freezer room)
- Disabled collision on ~100-150 items
- Significantly reduced the amount of particle emitters used for the frosty mist in the Freezer area (the particle emitters are also Particle FX items now (they used to be crabs))
- Removed several lights with huge radii and removed many smaller lights in areas with larger lights to reduce the amount of overlap
- Re-did IO modules for various functions to be less inefficient and weird
- All of these optimizations lowered the map's file size by ~4 megabytes

- Replaced canvas images (links expired), removed a Shotgun pickup in the lobby room, added Ranged pickups in the Lobby room, added a Special weapon pickup in the surveillance room

- Reassigned some weapon pickups, removed a single health pickup in the Freezer

- Resized the teleporter above the map so it should actually work for real now
- Added a photocopier and paper cups to the red meeting room & hallway
- Added very, very faint yellowish fog

- Added a teleport volume over the map so you can wander around in the singleplayer pre-match free roam mode
- Removed a couple pickups in the purple office hallway

- Added pickups around the map
- Added CTF flags (positions are placeholder)
- Added support for Oddball (certain doors close and the big central brain disappears)
- Shutter doors should 100% never ever show up when they aren't supposed to now
- Team spawns should 100% actually for real work now

- Quick fix to prevent shutter doors from showing up (i'm planning on them only being enabled in certain game types but that isn't a thing you can do currently)

- Team spawns should work now

- Security Doors now open on spawn, just in case they don't get forced open properly

Created item.
