	* gconf-property-editor.c (gconf_peditor_new_float_range)
	(gconf_peditor_new_int_range): Connect to value_changed signal

	* capplet-util.c: Comment out most of this file

	* gconf-property-editor.c (gconf_peditor_new_int_range): Convert
	to ~_float_range
	(gconf_peditor_new_float_range): Add callbacks for conversion
	between widget's values and GConf values in the signature
	(peditor_float_range_widget_changed): Issue callback, if
	available, to convert from widget's values to GConf values
	(peditor_float_range_value_changed): Vice verca above
	(gconf_peditor_new_int_range, peditor_int_range_widget_changed)
	(peditor_int_range_value_changed): Implement. Copy from float
	versions
