...uare also above the threshold

With the old behavior, monsters wander when they are on a square above the threshold, which means monsters would sometimes move to a square that they can detect is below the threshold. This change makes it so that a monster on a square above their scent threshold always moves to another square that is on or above their scent threshold.
