Ugly doors are doors that we don't want to see from the front:
- south-facing side of a BK door
- other side of one of those keyed staircases that don't actually have a matching key on the other side
This rejects layouts where one would appear.
Adds ability to make a location for required keys (enemy drops and pots), so the filler knows about them.
Uses the most pessimistic possible rule to make sure you can't keylock yourself in Escape.
Fixed graphics between HC/Sewers and cross dungeons.
Added base work for spiral staircases in HC/Eastern. (More data needed for other dungeons.)
Added new region to deal with push blocks in Sewers Secret Room
Refactored asm to be in multiple files.
