	* src/nautilus-application.c: (nautilus_app_quit):
	Used the fixed-up gnome_vfs_shutdown to properly synchronize
	with GnomeVFS threads that are still finishing up. Got rid of
	nautilus_app_real_quit and the other hacky code that I used
	to do this before gnome_vfs_shutdown was working properly.
	Got rid of a bunch of FIXMEs that are now take care of.

	* libnautilus-extensions/nautilus-directory-async.c:
	(cancel_directory_counts), (top_left_read_close),
	(cancel_top_left_read), (nautilus_metafile_read_cancel),
	(start_getting_directory_counts), (start_getting_top_lefts):
	Added cancel calls to the different GnomeVFS async tasks that
	can be running when opening a Nautilus window, called them
	from the NautilusDirectory destroy call.

	Nautilus now shuts down GnomeVFS jobs cleanly during a quit.
	There is still a problem where in some cases it will take a
	while before the async jobs go away. This seems to be because
	the corresponding NautilusDirectory doesn't get destroyed right
	away when a window is closed. I need to get Darin to help me fix
	this.
