NSImage+HHTint - Tints grayscale images using CoreImage

This category on NSImage adds a single method:

- (NSImage *)hh_imageTintedWithColor:(NSColor *)tint;

This method creates a tinted copy of the image. Colored / gray pixels of the original image lead to pixels of an equally dark shade of the tint color.

This code was originally written for Tembo.app. The navigation bar in Tembo is build from grayscale images. At runtime these are tinted to a dark blue. In Tembo's drill-down view the same process is applied to a stock NSSegementedControl to make it match the color of the navigation bar.
