	* app/gegl/Makefile.am
	* app/gegl/gegl-types.h
	* app/gegl/gimpcurvesconfig.[ch]
	* app/gegl/gimpoperationcurves.[ch]: add curves operation and its
	config object. Hack around badly to be able to use GimpCurve from
	app/core.

	* app/gegl/gimp-gegl.c: register the curves operation.

	* app/tools/gimpcurvestool.[ch]: added get_operation() implemenetation
	and use the new config object instead of keeping around 5 curves.
