Aiue:
	- Attempt at giving things more appropriate names. Also added support for RGB gradients, silly as they may be.
	- Added function Prism:Gradient(), rewrote :GetAngleGradient() to call this for backwards compatibility.
	- Removed unnecessarily silly conditionals from multiplicative saturate/brightness value functions.
	- Allow for multiplicative operations in the saturation/brightness manipulation functions.
	- Fix for :RGBtoHSV()
