Title: Add RGB Filter and add to showcase example, Fix documentation error

I added GPUImageRGBFilter which basically just lets you set a multiplier for the red, green, and blue values independently. It's very similar to the exposure filter in terms of design. I also added this to the FilterShowcase example project with a slider that will adjust the green value.

I also fixed a small issue with default values in the README documentation for the Vignette filter.

I did have to `#import` GPUImageRGBFilter.h in the FilterShowcase example for some reason. It wouldn't show up other. Not sure if I missed adding something there.
