Improved Cabin Away Mission (#45618)

* The map itself

I hope it won't PR on /tg/station immediately.

* ok lavaland monster dmi thank you

"bruh you added two sprites oh shit im about to m-m-m-malfuncti-" *BOOM*

* cabin building stuff

Still need to merge master.

* Ninja's uniform PR got merged.

Good thing I used, like, only one jumpsuit for the entire map. I hope this merges before someone changes winter coats though.

* lmao

* MrDoomBringer forgot a few things

obj/iced_abductor. that's an ayy lmao moment.

Besides that, the block should work. Just don't destroy it before the round begins otherwise you see this: https://i.imgur.com/K3GGnqy.png

Proof that this works: https://i.imgur.com/MxVO0Og.png

* no more claustrophobic medbay

It doesn't look as good as I want it to. It also feels way too fucking cramped.
