Implement <Someone>'s suggestion for addressing <Someone>'s
complaint about the inadequate feedback given when dipping a unicorn
horn into a potion to convert it into water. (Mainly, if the potion
has already been given a name, you won't be prompted to give it one
when dipping transforms it; if that was the last one you had, getting
"The potion clears." isn't sufficient to let you keep track of what
type of potion was cleared. You still have to keep track of such
stuff yourself, but now you'll get "The swirly potion clears." so you
at least don't have to start remembering or recording the type prior
to dipping.)
The hallucination handling isn't very useful; the description is
given will full accuracy by the immediately following inventory update.
