Added most of the mechanism to change the strips from color variations 

to color constants (i.e. red constant, green constant, blue
constant).  But I haven't hooked this up yet because the UI gets more
crowded and the arrows don't reflect the correct values.

Added "Go to Black" and "Go to White" buttons.
