front: Add get/put convenience functions to Profile class.
front: Use convenience functions in ControllerProfile.
res: Change the name of a few resources to match associated class.
front: Test mask colors in RGB 3-space.

The previous algorithm would enormously penalize errors in the red and
green channels:
 - red channel errors were magnified by 2^16 in the distance metric
 - green channels errors were magnified by 2^8 in the distance metric

This algorithm gets the independent RGB components and computes the
distance metric as the square of the pythagorean distance in cartesian
3-space.
