fix github issue #493 - hero item knowledge

Issue was about being asked what to call a previously seen potion
which has been picked up and thrown by an unseen monster.  Hero
shouldn't remember what the item description was.  This is a much
more general change than just fixing that.  Any item picked up by
an unseen non-tame monster will have all its *known flags cleared
since the hero can't see what that monster does to it.  Same if an
item is picked up while seen but then used when unseen.

Unseen pets are excluded from the pick up case--but not the use
case--because they pick up and drop stuff continually and players
would just slaughter them if they caused item information to be
forgotten.
