* components/adapter/main.c: (main): Use gdk_get_display, not
	getenv ("DISPLAY").
	* components/loser/content/main.c: (main): Ditto.
	* components/loser/sidebar/main.c: (main): Ditto.

	* components/tree/nautilus-tree-model.c:
	(stop_monitoring_directory): Rename back from
	stop_monitoring_directory_without_reporting. This no longer
	changes the state of "done_loading".
	(set_done_loading): New, handles a state change in either
	direction.
	(done_loading_callback): Moved most of the guts of this into the
	new set_done_loading.
	(start_monitoring_directory): Call set_done_loading explicitly.
	Before, this had to use an idle function, but this is no longer
	necessary since we use an idle function at the next level up.
