distributivgesetz 3645fa7d89 Replaces slime clone damage with a "Covered in Slime" status effect (#77569) 
## About The Pull Request

This PR replaces clone damage dealt by slimes with a new status effect,
"Covered in Slime".

The status effect is applied when you wrestle a slime off. The status
effect has a chance of not applying if your biohazard protection on your
head and chest is good enough.

It deals brute damage over time and gets removed when you stand under
the shower for about 10 seconds or when you are about to enter softcrit.

As a direct consequence of adding this feature I added showers to the
North Star and Birdshot Xenobiology Labs. I'm sorry, I'm sure you wanted
to make a statement with this, but we kind of require them in there now.

## Why It's Good For The Game

One source of clone damage eliminated whilst hopefully keeping a
"unique" interaction when dealing with slimes. No other source of clone
damage has been touched.

Clone damage is a damage type that shouldn't exist anymore, it's a relic
left from the era of cloning and it's so specific of a damage type that
it rarely gets used as a result. It really should be a type of
affliction (wound etc) instead of its own damage counter.

However, some things in the game still depend on clone damage being
around, so those needs to be addressed first.
We start off with slimes in this PR.

This status effect either lets you either continue with your work if you
react fast enough or it forces you to medbay, giving a victim more
control over the situation, as opposed to just being dealt a rare damage
type that always forces you to go to medbay if you want it healed.

## Changelog

🆑 distributivgesetz
add: Replaced slime clone damage with a "Covered in Slime" status effect
that deals brute damage over time and can be washed off by standing
under a shower.
add: Northstar and Birdshot Xenobiology have been outfitted with a new
shower.
code: Replaced the magic strings in slime code with macros. Also
included some warnings to anyone daring to touch the macros.
