Fixes the Sun/Weather and Ports Vore's Lighting SS
New lighting system is needed to handle updating literally 14k+ tiles whenever the sun moves. The straight port seems to have had no adverse effects from what I could see. Don't know if it's more performant but it doesn't seem to be less. I didn't expect the latter would be needed for the former.
