[Bastien Nocera <hadess src gnome org>]

    preferences: Bind some labels' visibility to their corresponding ranges
    
    The hue, brightness, saturation, and contrast labels have their visibility
    programatically tied to their corresponding ranges. We can do that in the
    .ui file more easily.
    
    Bind these labels' visibility to their corresponding ranges' in the
    preferences.ui file itself.
