Issue reported by Ryton: a sleeping orc caught a thrown gold piece.
Throwing one at some other sleeping monster woke it up.
That is actually intentional. Sleeping monsters with the 'greedy'
attribute will wake up without becoming angry and catch thrown or
kicked gold that is aimed at hit them. The fix here is to augment
the catch message to say so. Non-greedy monsters wake up and treat
it as an attack, but the gold always misses.
Both cases only happen for monsters who are asleep for an indefinite
period of time. Any monster that is asleep (or paralyzed, or busy
putting on armor) for N turns effectively doesn't notice. If it can
be seen, the gold "harmlessly hits" (if it can't be seen, the gold
misses), and the target continues doing--or not doing--whatever it
is doing. That's suboptimal; another case where lumping multiple
can't-move situations into a single monst->mfrozen countdown timer
causes timed sleep to be indistinguishable from timed paralysis.
