Hoarfrost: Snow & Blizzards

Fixed

• The haze of heavy snow and blizzards now covers the distant land of Distant Horizons too. It used to end at the vanilla render distance, leaving the far land clear and green behind a hard edge; now the near and the far land fade into the storm alike.
• With LambDynamicLights the lying snow is lit by torches in hand, glowing mobs and other moving lights like the ground around it, instead of staying dark.
