fix scatter feedback

Reported directly to devteam (for 3.4.3 but still present in 3.6.0):
an unseen landmine explosion which caused scatter() to break a
boulder or statue would give feedback as if the hero could see the
boulder or statue being destroyed.

Also, a couple of landmine explosion messages didn't take deafness
into account.
