temporarily fix buggy item descriptions (PleasingFungus)
Add Bloax's obsidian statue tile.
Hide a hack better.

I'm not convinced this hack is necessary at all, despite what a comment
in monster::body_weight claims; there doesn't seem to be anything
with CE_NOCORPSE that has a corpse, and it isn't referenced at all in
the blood potion/biting code.
don't fail if there are no files
