	* app/core/Makefile.am
	* app/core/core-types.h
	* app/core/gimpcurve-save.[ch]
	* app/core/gimpcurve-load.[ch]
	* app/core/gimpcurve.[ch]: new GimpData subclass which keeps a
	curve as known from the curves tool. Pretty much unfinished, but
	can do everything that used to be done by base/curves.c and more.

	* app/base/curves.[ch]: stripped down to plain arrays of
	uchar (the actual curve) and the LUT setup function. All the rest
	is done by GimpCurve now.

	* app/tools/gimpcurvestool.[ch]: use an array of GimpCurves
	instead of the old Curves cruft. Use Curves only for the last step
	of creating the LUT. Pretty much unfinished migration here too.

	* tools/pdbgen/pdb/color.pdb: use a GimpCurve here too.

	* app/pdb/color_cmds.c: regenerated.
