add delayed_selection to _EShellViewPrivate. (new_folder_cb): new

2000-08-31  Chris Toshok  <toshok@helixcode.com>

	* e-shell-view.c: add delayed_selection to _EShellViewPrivate.
	(new_folder_cb): new function.  check if the path is our
	delayed_selection and if so, select it.
	(folder_selected_cb): if the user selects something using a UI
	gesture, clear out a pending delayed selection.
	(e_shell_view_display_uri): if the uri isn't available, save it in
	the delayed_selection field, and set up the new_folder signal.
