Combat detection fixed for solo

Playing any kind of dungeon alone is a pain, especially in the catacomb where, upon detection, the entire room will instantly zero in on you. It could be nice if either the basic skeletons or the immediate surrounding got alerted, but not the entire bloody room. I died very often because I expected a dark room to be empty, only for one monster to notice me, immediately raise the alarm, and causing my agonizing demise through bone dog bites and scythes to the face.
