Add new color mode setting

Replace the "vivid" mode setting with a new 3 choice screen:
- Natural (sRGB)
- Boosted (sRGB + 10% saturation)
- Saturated (unmanaged, colors are assigned the native color space)

The "Colors" setting that replaces "Vivid" only appears on devices
that support wide gamut rendering and color management. Changing
the color mode has an immediate effect and triggers a configuration
change in running application so that applications that request
wide color gamut rendering can react properly (since they lose
that ability).
