## About The Pull Request This PR changes `TRAIT_SPACEBREATHING` from a lung trait to a mob trait, and simultaneously renames it to the much less snappy but simultaneously more specific `TRAIT_NO_BREATHLESS_DAMAGE` This proc technically does not allow you to breathe specifically in space, it only bypasses any checks for minimum levels of gases regardless of if you are in space or not At the same time I implemented it for basic mobs, just because I can. I don't think they have any way of gaining it, but if some future dev was going to make a temporary buff that lets something breathe in space now it could also work on basic mobs. ## Why It's Good For The Game This is how developers expected the trait to work and no longer requires that the mob have lungs to be used ## Changelog 🆑 fix: Changelings with Void Adaption can once again breathe in space /🆑
