	* app/actions/view-actions.c: changed zoom actions to be
	GimpEnumActions using the GimpActionSelectType enum. Enables
	keyboard shortcuts for useless stuff like "zoom out a lot", and
	makes them better accessible for external controllers.

	* app/actions/view-commands.[ch]: renamed view_zoom_cmd_callback()
	to view_zoom_explicit_cmd_callback(), removed the zoom_in and
	zoom_out callbacks and added a new view_zoom_cmd_callback() for
	the new GimpActionSelectType-based actions. The implementation of
	the new zoom types is questionable but now there is a place where
	nomis can fill in nice formulas...
