Subject: [PATCH] Stop monsters from interacting with protected items on the
 floor

This fixes the issue of chests with the wand of wishing on the castle level
being stolen by soldiers.

Commit b12ea03d1 revealed that searches_for_item() didn't check for onscary()
and allowed monsters to pick up items even though they were protected by a
scroll of scare monsters.
