Hatch pathing broken

1. Horizontal hatches don't work.
2. Manual hatch can't be opened from above or below;
3. Dupe can't even jump above it - it needs a ladder;
4. However, dupe walks below the hatch in a corridor of height "2" without problems

I haven't applied any special door permissions - all hatches are on auto. "3." was an issue in an actual game... until I died to heat.

I've also had problems with <-> permissions on normal doors, but can't reproduce it right now, so if I see it I'll post.

Also Hatches(critters) sometimes CAN pass through open doors(state is "Open", not Auto), I think it happened when the door was 1 tile below the floor height, however i can't reproduce that either.
