Changes how destroying turfs works

Turfs now have a baseturf var which determines what is "under" every
turf. The default is space.

Actions that previously did changeturf(/turf/space) (like bombs or RCD
deconstruction) now do changeturf(baseturf). Functionally the same for
the station, but allows special turf types that don't break to space
(such as planet tiles).

Right now the asteroid tiles are the only thing with a baseturf other
than space (the baseturf is an asteroid tile).

Baseturf is tracked when new things are built, so building a floor and
then a wall on the asteroid tile, and then bombing that wall will return
it to an asteroid tile, not space.

Allows building on asteroid tiles now that doing so wont randomly make
holes to space. Time for giant mining forts.

I should have done this years ago for away missions.
