	* app/core/Makefile.am
	* app/core/gimpgradient-load.[ch]
	* app/core/gimpgradient-save.[ch]
	* app/core/gimpgradient.[ch]: moved gradient file handling out of
	gimpgradient.c to new files.

	* app/core/gimp.c
	* app/actions/gradients-commands.c: changed accordingly.

	* libgimpcolor/gimpcolor.def: added gimp_rgb_parse_name.
