	* libgimp/gimpdrawablecombobox.c
	* libgimp/gimpimagecombobox.c
	* libgimp/gimpmenu.c: changed the label for the empty menu from
	"None" to "Empty" since that's what GTK+ uses.

	* libgimpwidgets/gimpintcombobox.[ch]: added convenience function
	gimp_int_combo_box_connect().

	* plug-ins/common/bumpmap.c
	* plug-ins/common/compose.c
	* plug-ins/common/depthmerge.c
	* plug-ins/common/displace.c
	* plug-ins/common/lic.c
	* plug-ins/common/warp.c: ported to GimpDrawableComboBox.

	* plug-ins/Lighting/lighting_ui.c
	* plug-ins/MapObject/mapobject_ui.c
	* plug-ins/common/sample_colorize.c: use
	gimp_int_combo_box_connect(). This restores the correct behaviour
	of setting the drawable_ID to the first drawable from the list if
	it's invalid.
