[Fixed] Stairbuilding crush behavior (Cyberdreams MAP19)

[Xavier Drozzlewore]

stairbuilder specials 127 (and possibly others?) should crush. this breaks Cyberdreams MAP19, as the switch does not crush the cyberdemons that block your path.

The ->crush field is never initialized in vanilla doom.

The probability that the ->crush field contained a 0 in it was low, so usually lead to the floors crushing. Doomwiki lists the specials as crushing specials.

Choco hardcodes this to always crush:

if a fix isn't possible, suggesting a compat flag

oh issue appears to be that it crushes for 1 tic and then stops crushing?

fixed. This used the wrong crush mode.
