commit e0aa5b31f6829a3fa9727d8b23054697c8ea6e5c

plug-ins: Enable export of original Duotone data
Optionally includes the previously saved
Duotone color space data on PSD export.
New load dialogue alerts user if duotone data was imported.
New export dialogue appears if the image is still grayscale and
the parasite exists.
If selected, the mode is set to PSD_DUOTONE in the header and
the original duotone data is written in the color space section.
