Batch Seventeen: Less Regular Diagonal Corridors

When I fixed the lollipop room's diagonal corridors to be walkable without squeezing, I did it in an entirely regular way, making them always two tiles wide. For this update, I introduced the possibility for some (not all) of them to be less regular, but still walkable, by allowing them to sometimes switch between advancing vertically first or horizontally first. (They're still basically just a diagonal corridor and noticeably different from the barbell corridors. But they can be just a little jagged in places now.)

Additionally, I tweaked the unfilled-level formula just a bit more.

Finally, I tried out a new size for this batch, smaller than the previous couple of batches, but still larger than NetHack's cramped little levels.
