    libgimpcolor:  use g_debug for informational "using babl ..." messages
    
    We sometimes can get a lot of informational messages like:
    gimp_color_transform_new: using babl for 'sRGB IEC61966-2.1' ->
    'GIMP built-in sRGB'.
    After discussion on IRC there is agreement to use g_debug for these instead
    of g_printerr.
    This way they can still be seen with GIMP_DEBUG=LibGimpColor, but won't
    clutter the console when looking at something else.
    
    Note that this only changes the informational message. All the error
    messages are left alone as g_printerr.
