Night clouds: Boost brightness for a moonlit appearence (#7748)
Previously, night clouds were almost indistinguishable from night sky, especially since a recent commit that made night sky brighter. They were lacking the beautiful luminosity caused by being lit by the permanently-full moon. When 'directional_colored_fog = false' allow the dawn/dusk cloud brightness boost to apply through the night too. Set an identical minimum cloud brightness for when 'directional_colored_fog = true'.
