2008-07-15  Christian Neumair  <cneumair@gnome.org>

	* libnautilus-private/nautilus-dnd.c (slot_proxy_drag_motion),
	(nautilus_drag_slot_proxy_init):
	Also support a mode where the target URI is NULL, and the target slot is
	set.

	* src/nautilus-notebook.c (build_tab_label):
	Set up notebook labels as slot drag proxy, replace old DND code.
