Fix mapper lag

[weisluke]

previously, if the mapper completely lost track of where someone was in the dark or blind, it would search through all rooms on the map. unfortunately this causes noticeable lag for the user, so that ability was removed. Now, if the mapper loses track of you in the dark or blind, it will stay lost until you enter a lit room.
