Allow People to re-enter the arrivals shuttle

[misto]

so you cant get onto the arrivals shuttle itself to harm late joiners, no big deal. just make the arrivals hallways/maint just outside it into your killzone and camp it and youve got an identical effect.

if you spawned them or teleported them into the various bedrooms/break rooms/hobo camps around the station at least antags would have to put a little more effort into blowing up all the various spots
