Fix looking up attacker actor, which observers may not see
Mark on the main screen when leader hidden in the dark
Show item name in cursor and target description
Make caves dark more often now that light sources exist
Make PersLit a lazy EnumMap

This makes a difference, but only with lots of light sources
in the dungeon.
Keep AI conditions lazy, because not all are checked
Don't mark target position with inverse video
Display both path and line length for cursor and target
Add target monster HP indicator
Prefer displacing projectile to hitting it
Don't announce creation of a projectile

Usually this is duplicated with the report of an actor aiming
the projectile. In the rare cases when the actor is not visible,
stopping playback and running must suffice.
Give some more info when an actor dominated
Prevent AI from being fooled by a pillar dance
Add the source faction id to SfxEffect atomic command
Report domination both to the old and the new faction
