Title: Mark (E)xplored on Overmap

This adds a new option to the overworld map that allows players to mark locations as 'explored'. This turns the symbol color for a marked tile to dark gray while overlays or blinking is enabled. This provides a more at-a-glance representation of places you have and haven't cleared out yet.
