Fog of war is easier to see, and admin-configurable

The first pass at shading unexplored space used a dark overlay, which barely showed up against a map that's already nearly black — in practice, close to invisible. It's now a light gray at high opacity by default, so the line between what you've scouted and what you haven't is obvious at a glance.

It's also now a setting, not a fixed color. From the Admin page's Game Settings tab, under "Fog of war overlay," an admin can pick the color from a palette of neutral tones and set the opacity with a slider. Like the other game settings, a change applies to games started after it's saved.

Play a fog-of-war game to see it.
