core: Add simulation intent and BPC to GimpImage
Adds a simulation_bpc and simulation_intent to GimpImage to allow plug-ins to access it for CMYK import/export. Four pdb functions were added to enable this access: image_get_simulation_bpc (), image_set_simulation_bpc (), image_get_simulation_intent (), and image_set_simulation_intent (). Next, it updates menu options and code to support GimpImage's internal simulation intent and bpc. New 'simulation-intent-changed' and 'simulation-bpc-changed signal are emitted via GimpColorManagedInterface so that relevant tools (such as the CYMK color picker, GimpColorFrame, and future pop-overs) are aware of these changes.
