Call potion bottles by nonsensical names if hallucinating

From SliceHack. Note that this refers to the description of the physical
bottle; it's a substitute for "phial", "carafe", "flask", etc. such as
are seen when a potion crashes on someone's head. They don't obscure the
randomized appearance or actual potion identity.

The SliceHack version evidently went through several revisions; just
take the current one.
