Somewhat un-nerf D:9-16 OODs/vaults, change OOD-only D spawns

When dungeon-split was first started, it cut off a large part of D out-of-depth
spawns both due to obsolescence and helping distinguish Depths from D, but
this (inadvertently?) heavily nerfed any of the many, many traditional vaults
using 098, as well as out-of-depth spawns per floor.
For the most obvious example, the four most common spawns of the lowest OODs for
D:14-16 were yaktaur captain, stone giant, glowing shapeshifter, and ettin, but
in the interim period between before the creation of Depths and this patch
the same tier has four most-common spawns of zombies, hill giants, ugly things,
and centaur warriors.

This expands the ood-cap to make the super-ood 8s for D:8-16 dangerous
again, but not going far enough to spawn some (now) Depths and Vaults only
terrors like titans and golden dragons, thus still distinctly splitting
D, Vaults, and Depths from each other.
The old-D:1-27 monster set was thus rebased around that ood-cap, adjusted
for monsters that mostly only spawn as oods, and then edited further
for organization purposes. The patch also has some experimental rare new
super-ood spawns to compensate for the biggest danger cut-offs.
