Toughen up floors

[Sex_Robot]

With the new atmos changes, the tiniest explosion can cripple an entire station with a combination of lightning fast 02 damage with the temp drop slowing you down can mean that you get held in place as the vacuum drags you back as fast as you walk away meaning that death is a given. An Antag with an implanted bomb which detonates when they die can open a single tile. It can result in a pile of antag stuff in a blast radius surrounded by 2-3 people all dead from 02. A hole outside medbay pretty much means that nobody is getting to medbay. It wouldn't be so bad if repairing floor holes wasn't so hit and miss and repressurising worked properly.
