Cryokinesis and Geladikinesis mutations (#42453)

* Adds cryokinesis and renames the cold resistence file to space adaptation

* adds cryokinesis

* fixes icon conflict

is there actually a proper way to fix them thats not copying master and reimplimenting your own sprites?

* fixes a typo and lowers instability of cryokines by 5

* Apply suggestions from code review

* maybe reverts line ending?

* unfucks flags?

* probably unfucks line endings

i swear to fucking god why does it even do this. i never even touched the file and reverting it to master doesnt do anything. fuck you git
