Liminal zone send-off

Today I'm making the final update for liminal zones, it's my first ever map, and after finally fixing many of the lighting issues present on the map, I am giving it the final updates that I believe it rightfully deserves before abandoning the project entirely

Here's an outline of what to expect:

- entity toggle (was a thing I originally intended for)
- teleport system (for every unique area)
- portals to other maps of mine
- avatar rack
- Post Processing Toggle

The entities will include:
- Howler
- Smilers
- Julian

There will be a secondary toggle for the ai, where it will increase the walkspeed, and enable ai for a more chase oriented experience, much like nextbots
