	Fix gegl types and includes so we can include operations from
	app/gegl in other gimp files (needed soon):

	* app/gegl/gegl/gegl-types.h: not copied from gegl any longer.
	Now contains only two typedefs needed by the copied operation
	headers.

	* app/gegl/gegl-types.h: include above types file.

	* app/gegl/gimp-gegl.c
	* app/gegl/gimpoperationcolorbalance.c
	* app/gegl/gimpoperationcolorize.c
	* app/gegl/gimpoperationdesaturate.c
	* app/gegl/gimpoperationhuesaturation.c
	* app/gegl/gimpoperationlevels.c
	* app/gegl/gimpoperationposterize.c
	* app/gegl/gimpoperationthreshold.c
	* app/gegl/gimpoperationtilesink.c
	* app/gegl/gimpoperationtilesource.c: include only <gegl.h> and
	"gegl-types.h" from this directory, which is much more gimpish
	now. Include "gegl/buffer/gegl-buffer.h" in the source and sink
	operations.

	* app/tools/gimpimagemaptool.h: warn about inclusion of <gegl.h>
	only if it hasn't been included before, so it only warns in the
	files where we still have to address this issue.
