directory)

	Note that this is only done when in "use separate windows
	for everything" mode. My brain broke trying to figure out
	how it could be used coherently in single-window mode.

	* libnautilus-extensions/nautilus-gtk-extensions.h:
	* libnautilus-extensions/nautilus-gtk-extensions.c:
	(sanity_check_window_geometry): New helper function, takes
	four coordinates and munges them if necessary to keep the
	window at least partially on screen and not ridiculously
	huge.
	(nautilus_gtk_window_set_initial_geometry): New function,
	sets the position/location of a window before it is shown
	after calling sanity_check_window_geometry on
	top/left/width/height parameters.
	(nautilus_gtk_window_set_initial_geometry_from_string):
	New function, calls _set_initial_geometry after parsing
	geometry-as-string parameter and adjusting it for
	minimum-width and minimum-height parameters.

	* libnautilus-extensions/nautilus-metadata.h:
	#define new per-directory key for window geometry

	* src/nautilus-application.c:
	(nautilus_window_delete_event_callback): New function,
	calls nautilus_window_close.
	(nautilus_application_create_window): Hook up this new
	callback as signal handler for window's delete_event;
	this causes closing the window from the close box go
	through the same nautilus_window_close path that closing
	the window from the menu did.

	* src/nautilus-bookmarks-window.c:
	(nautilus_bookmarks_window_restore_geometry):
	Now calls nautilus_gtk_window_set_geometry_from_string,
	which was extracted from here.

	* src/nautilus-window-manage-views.c:
	(position_and_show_window_callback): New function, reads
	geometry string for this location from metadata & applies
	it (if in use-new-window mode), then shows window.
	(nautilus_window_end_location_change_callback):
	Use nautilus_directory_call_when_ready to show the window
	only after the metadata has been read, so it doesn't appear
	in one position and then bounce elsewhere.

	* src/nautilus-window-menus.c: (file_menu_new_window_callback):
	Removed gtk_widget_show from here. It wasn't necessary since
	the window is shown later after the URI is determined to be good,
	and doing it here prevented the window positioning code from
	working correctly.

	* src/nautilus-window-private.h: Moved some window geometry
	#defines in here.

	* src/nautilus-window.c:
	(nautilus_window_save_geometry): New private function, reads
	the window geometry and stores it in the directory's metadata.
	(nautilus_window_close): Calls nautilus_window_save_geometry
	if we're in use-new-windows mode.
