Fix 2063470: =f inscription preventing wielding of stones

Improve exclusion los behaviour.
* now takes into account what the player knows of the map
* don't autoremove exclusions if you don't know the monster died
* the los gets updated as the player explores the area

For some reason this doesn't work when you dig into an excluded area.

FR 2006559: Sort monsters in description menu (?\) using the same
measure as the monster list does.
