Adds explosive immunity to stairs

[OuterMostMonk]

Effectively makes stairs immune to destruction.

Stairs are often fought over as they make a good defensive location, grenades are good to push anyone camping the stairs off of them for a bit, but two grenades or so are enough to destroy the stairs.

This can lead to scenarios where assaulting or escaping from a location becomes incredibly difficult, particularly if you are trapped on the lower level.

Uncertain if ladders should be made immune as well, if it is desired, I can add that too.

I'll let XO and James figure this one out, but i think it'll be great balance-wise, particularly for locations like the second floor medical bay where you can easily cut off the staircase and turn it into a fortress.

This is a good idea, although it makes me wonder if a tactical ladder would be a good idea to implement.

Being able to destroy key points like stairs should be fine to do, if anything we need could just add onto engineering features to allow ladders or stairs to be made!
