	Fix 4221 (Pressing Cancel button does not cancel)

	* libnautilus-extensions/nautilus-file-operations.c:
	(transfer_dialog_clicked_callback), (handle_transfer_ok):
	Redo cancellation to use a flag in the Transfer state and
	return a request to cancel during the next callback instead
	of issuing a gnome_vfs_async_cancel and destroying the
	dialog. The latter approach would now work too with my
	latest change to gnome_vfs_xfer, this new way of cancelling
	is cleaner and causes all the item that actually do get
	copied to show up in their new locations.
