[MIRROR] Adds the Ectoplasmic Outburst, a rare ghost-centric anomaly event [MDB IGNORE] (#19292)

* Adds the Ectoplasmic Outburst, a rare ghost-centric anomaly event (#73024)

## About The Pull Request

This PR description might be a bit rushed because I accidentally
submitted the PR and want to bang out a quick explanation of what this
is before people start asking questions.

Adds a new, rare, ghost-themed anomaly event -- The Ectoplasmic
Outburst.

![Animation](https://user-images.githubusercontent.com/28870487/215292488-cc5ce589-39be-490d-bd80-92a2ed6e948b.gif)

This event increases in power as more ghosts orbit it, with three
important thresholds to meet.

If 10% or more of all active observers are orbiting the anomaly, an
effect will occur in the nearby area akin to the revenant's defile
spell, damaging flooring, windows, and making a mess.

If 35% or more are orbiting the anomaly, nearby objects in the effect
radius have a chance to become haunted, and will fling themselves at
anyone nearby for a bit. Spooky!

Now, at 50% or more participation, things get serious. Ghosts orbiting
the anomaly will be polled to be brought back into the world for a brief
period as a vengeful spirit, anchored to a SUPER spooky ghost portal.
The portal closes after two minutes (alternatively, smash it with a
toolbox) and deletes all of the ghosts it spawned. Vengeful spirits are
mostly just meant to smash stuff and be a nuisance while they can. It's
a wonderful opportunity to let deadchat desalinate a little.

![spooky
ghosts](https://user-images.githubusercontent.com/28870487/215293550-f7bbede2-cfa0-49b1-87fe-f38ee45d1df8.gif)

Oh, also, the anomaly is deadchat controlled. With enough ghosts, you
could theoretically outrun anyone trying to neutralize it!

The associated reactive armor has an effect similar to the anomaly,
haunting nearby objects for a time when the wearer is struck. Not
particularly outstanding, but it can introduce an element of chaos into
a fight that your opponent might not expect.

## Why It's Good For The Game

Anomaly events are great for ghosts. Why not make one tailored just for
them!

Gives admins something to spawn when a wizard has killed half of the
crew but it's not quiiiite time for an ERT.

It's a bit of a silly event with a novelty reward, but I think it's rare
enough not to be a huge issue.
