Transform the lower half of D into a new branch: the Depths.

D is now 16 levels (the unsealed part was 14 levels previously), and the
Depths are six levels.  Vaults is enterable from Depths:2-5; Abyss, Hell,
and Pan portals are available for the entire length of the branch.

Right now the monster set is identical to Vaults except for the absence
of Vaults-specific humans.  D's monster set has also been truncated,
mainly on the out-of-depth front. It's my intent that this serve as a
starting point for figuring out what monsters we want to split between
the two branches.
