	* app/config/gimpcoreconfig.[ch]: add "use-gegl" property but
	don't serialize it.

	* app/widgets/gimptoolbox.c: add super ugly "Use GEGL" toggle to
	the toolbox so we don't need to have prefs open all the time when
	experimenting with gegl.

	* app/tools/gimpimagemaptool.[ch]: remove "Use GEGL" toggle from
	the tool dialogs and connect to the config property instead.

	* app/core/gimpdrawable-desaturate.c
	* app/core/gimpdrawable-invert.c: made them runtime-switchable by
	looking at the config property.
