If the baalz level got transposed during creation, the fixup for
a decorative portion of the map didn't work properly. Monsters
eligible to be created at pool locations could end up trapped in
a couple of inaccessible locations.
[To be fair, the baalz hackery predates level flipping....]
Closes #598
(already implicitly excluded because randomly generated artifacts are
all weapons and containers don't start with any weapons in them)
don't give lance or mattock as starting equipment when creating soldiers
+fixup for the insect "legs" (some extraneous walls inside solid stone) on the
+ baalz level didn't work as intended if that level was flipped
