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.
This is how developers expected the trait to work and no longer requires
that the mob have lungs to be used

fix: Changelings with Void Adaption can once again breathe in space
