Turns space bat into a basic mob & moves retaliate mobs to retaliate folder (#74747)

## About The Pull Request

Turns Space Bats into a basic mob, why not.

I also noticed some retaliate mobs weren't in the retaliate folder, and
moved them over. I didn't move goats over because they're in a large
file and didn't want to really expand much on this PR that I just wanted
to focus on just bats.

## Why It's Good For The Game

I was just messing around with some bat stuff and thought I might as
well make them basic mobs.
