Fix 1869850: Targeting now respects mimics' (un)known status correctly,

             so that * and / work for unknown ones, and + and - for known
	     ones. Also, mimics become known if you hit them since the
	     resulting message ("moderately damaged" or "looks slightly
	     unstable") will give that away anyway.

Implement the first part of FR 1903048: Added a range parameter to
direction(), so that when targeting for weapons of reaching we can check
whether a monster is within the range of 2 squares (grid_distance).
Does not handle submerged monsters.
Eventually, this could be used to also limit max range for certain spells
(Freeze, I'm looking at you!)
