	* app/config/gimpconfig-utils.[ch] (gimp_config_connect): make it
	a two-way connection and added a property_name parameter so it
	can be used to connect only a certain property.

	* app/tools/gimptexttool.c: changed accordingly.

	* app/tools/gimphistogramoptions.c: use gimp_config_connect().
	Changed the default histogram scale to linear.
