Heed other hazards when bumping the Wumpus

When you bump the Wumpus by moving into the room where he is, most of
the time he moves to another room rather than staying and eating you.
There can be other hazards in the same room since he is not bothered
by them, and those should also cause you to get affected.  Check the
room for other hazards after bumping the Wumpus in the event he moves
out of the way.
