More Darkness 2.0.0

New: the mod now simulates the human eye.

• Eye adaptation (eyeAdaptation, on by default): eyes slowly adapt to darkness and reveal your close surroundings only; distant darkness stays black. Vision turns colorless in the dark. Leaving darkness abruptly is blinding for a moment.
• Darker water (darkerWater, on by default): water is murky, above and below the surface. Swamps hide everything, warm oceans stay clear.
• Smoother light falloff around torches, and smooth lighting on water surfaces.
