Quest NPCs turn blue and stop facing the hero once their quest is done

A dialog's quest comes from the game's script labels ("Dialog:<name>",
quest at +0x48). When that quest is done and not in progress, IsQuestNpc
answers false (blue on the minimap) and the idle action's type check
skips the turn towards the hero.
