Fix the use of lazy positioning, and the saving of metadata for
	lazily-positioned icons.  Fixes
	http://bugzilla.novell.com/show_bug.cgi?id=174766.

* libnautilus-private/nautilus-icon-container.c
	(icon_set_position): Clear icon->has_lazy_position, since the icon
	will be positioned once this function exits.
	(finish_adding_new_icons): Do not ignore already-placed lazy
	position icons when filling the placement grid!  Save the value of
	icon->has_lazy_position before calling assign_icon_position().
	Since that function may call icon_set_position() (which will clear
	the flag), we need to keep the original value of the flag.
	(finish_adding_new_icons): Don't clear icon->has_lazy_position
	here; let icon_set_position() do it.
	(finish_adding_new_icons): Emit the icon_position_changed signal
	so that the parent knows that we moved an icon under it.  This has
	the effect of updating/preserving the position metadata for
	has_lazy_position icons.
