Make wands of speed or slow monster known if their effect
on monsters is observed; likewise for speed boots. Also, avoid
giving odd "the bat is moving faster" when seeing a bat created
in gehennom and inaccurate "the monster is moving slower" when
a monster puts on speed boots.
Duuuh. Of course adding objects already changed the editlevel.
Anyway, here's the fix I was working on. It only matters in a very obscure
situation. (Also, the quest leader still speaks no matter what he's
polymorphed into.)
