        * libgimpcolor/Makefile.am
        * libgimpcolor/makefile.msc
        * libgimpcolor/gimpcmyk.[ch]: new files that define a GimpCMYK
        structure similar to GimpRGB.

        * libgimpcolor/gimpcolortypes.h: added the GimpCMYK typedef.

        * libgimpcolor/gimpcolorspace.[ch]: added conversions between RGB
        and CMYK. This implementation is the naive approach without any
        color calibration whatsoever.

        * libgimpcolor/gimphsv.[ch]
        * libgimpcolor/gimprgb.[ch]: purely cosmetic changes.
