Fix Oversaturation and Undersampling

Vibrant visuals is supposed to be vibrant but right now there is no way to adjust the saturation and it is currently so saturated that some block palates look WORSE in vibrant visuals, also even on max settings it is severely under sampled which causes a grainy look and things to kind of change and flicker in motion. to fix these problems add a slider for saturation and another one for lighting samples, if this slider already exists pleas make it go higher because if i have the graphical computing power to run it i should be able to have enough lighting samples that it doesn't look horribly grainy.
