* Closet Anomaly station trait. (#81393)
## About The Pull Request
Well, it's a station trait that makes a small number of (non-secure)
closets function as if splashed with eigenstatium (which turns them into
teleportation cabins of some sort). However, they're subtler, they lack
the transparency and blueish tint, and don't make sparks.
This PR also demotes the Eigenstate subsystem to a singleton global
datum. It doesn't fire, it doesn't init, it plain doesn't belong amongst
the big boys.
## Why It's Good For The Game
This should be a mildly interesting station trait.
## Changelog
🆑
add: Added a 'Closet Anomaly' station trait, which links and turns a
portion of the roundstart closets into impromptu teleporters.
