Shuttle doors

[KikiMofo]

partly i think this is an issue with how lightning-fast hacking and welding is - maybe you *shouldn't* be able to seal yourself off in <5 seconds even outside of shuttle contexts
idk if I have real suggestions to change those mechanics though, i think outside of that unhackability for interior shuttle doors sounds ok

I think I remember someone had a neat door welding animation and if doors used that for welding then it would just take the amount of time the animation plays out.
