move color conversions into utility file, add tests for color

[cambridgemike]

I created a new utils directory and put the color conversion methods in there, not sure if that's okay, I could move it back into p5.Color if you'd rather keep it all together.

Adds a bunch of tests for the p5.Color class and for the color conversion methods.

I'm trying to set pixels on an image with the var returned from color() but it won't take. The set method only works for me if I get() a pixel from an image loaded from a file, and use that to set a pixel in the new image. I can change the values in the pixel array but would prefer to not have to load an image to get the right data structure (from img.get())

Any advice on how to set a pixel in an image with color() is appreciated!

Using the latest p5.js download...
