Return a gboolean saying whether or not the shortcut changed. Use strcmp

	* e-shortcuts.c (shortcut_item_update): Return a gboolean saying
	whether or not the shortcut changed. Use strcmp rather than
	pointer comparisons to determine this.
	(update_shortcut_and_emit_signal): propagate the gboolean from
	shortcut_item_update (and only emit the signal if it's TRUE).
	(update_shortcuts_by_path): Only call make_dirty if something
	changed.
	(storage_set_new_folder_callback,
	storage_set_updated_folder_callback): Don't call make_dirty:
	update_shortcuts_by_path will have called it if necessary.

	* e-shell-view.c (updated_folder_cb): Don't call
	update_for_current_uri if the folder that was updated isn't the
	one being displayed.
