* thunar/thunar-view.{c,h}: Add new methods get_visible_range() and
	  scroll_to_file().
	* thunar/thunar-standard-view.c: Implement get_visible_range() and
	  scroll_to_file(). Drop the scroll_offsets, will be handled in
	  ThunarWindow.
	* thunar/thunar-window.{c,h}: Remember the first visible file whenever
	  leaving a directory and scroll to it when entering the directory
	  again.
	* thunar/thunar-application.{c,h}: Return the created window from the
	  thunar_application_open_window() method.
	* thunar/thunar-dbus-service-infos.xml, thunar/thunar-dbus-service.c:
	  Add DisplayFolderAndSelect() to the org.xfce.FileManager interface.
	  File managers that cannot scroll and select to a given file can
	  silently ignore the filename parameter and handle it like an
	  invocation of DisplayFolder(). Bug #1553.
