	* libgimpwidgets/gimpenumcombobox.[ch]: added new constructor
	gimp_enum_combo_box_new_with_model(). Also override the "model"
	property to make it clear that GimpEnumComboBox expects to be
	used with GimpEnumStore.

	* libgimpwidgets/gimpwidgets.def: updated.

	* app/tools/gimpcurvestool.c
	* app/tools/gimplevelstool.c
	* app/widgets/gimpwidgets-constructors.c: use the new constructor.

	* libgimpwidgets/gimpenumlabel.h
	* libgimpwidgets/gimpenumstore.h
	* libgimpwidgets/gimpintcombobox.h
	* libgimpwidgets/gimpintstore.h: use "parent_class", not
	"parent_instance" when including the parent struct.
