Skylight Hooks for Minecraft Forge

World Hooks on sky light, which can provide sunlight / moon factor from the Worldprovider.
mainly for Solar/Lunar Eclipse.

getSunBrightnessFactor is for getting sun brightness, i think it is better than just using getCelestialAngle.. I don't see any problem on it.
Seriously WHAT THE HELL IS THIS AND WHY IS I HERE. 
There is NO explanation of it in the code anywhere, it not referenced from anywhere, you are doing nothing with it, it has 'random' code in it what the hell is it.
