Michael Natterer ec196a8ac4 app: allow to set a color for GimpCurveView's primary curve
and redo how the curves tool sets its curves in order to support this
without code duplication. Also change the color of the yellow curve in
the dynamics output editor to orange because yellow is hardly visible.
