	* app/widgets/gimpcontainercombobox.c: correctly get the default
	GimpContainerViewInterface implementation and chain up to it for
	clear_items(). Update the preview renderers on "update", enable
	deselecting everything.

	* app/widgets/gimpimagedock.[ch]
	* app/gui/file-new-dialog.c
	* app/gui/palette-import-dialog.c
	* app/gui/preferences-dialog.c
	* app/gui/stroke-dialog.c: use GimpContainerComboBox instead of
	GimpContainerMenuImpl.

	* app/gui/palette-import-dialog.c: cleanup.
