them is not yet implemented.

	Did some cleanup on the new renaming code.

	* nautilus-glib-extensions.c:
	* nautilus-glib-extensions.h:
	Added nautilus_g_list_exactly_one_item and
	nautilus_g_list_more_than_one_item. These are more-efficient
	versions of g_list_length (x) == 1 and g_list_length (x) > 1.

	* nautilus-icon-canvas-item.c:
	(draw_or_measure_label_text): Add a line break between the
	editable text and the additional text.
	(nautilus_icon_canvas_get_text_bounds),
	(nautilus_icon_canvas_get_editable_text_bounds),
	(nautilus_icon_canvas_get_editable_text),
	(nautilus_icon_canvas_set_renaming):
	Replaced g_assert with g_return_if_fail calls, and added the
	complete set of g_return_if_fail.
	(nautilus_icon_canvas_set_renaming): Don't update the item
	unless the renaming state has actually changed.

	* nautilus-icon-canvas-item.h: Fixed formatting.

	* nautilus-icon-container.c:
	* nautilus-icon-container.h:
	Added nautilus_icon_container_set_auto_layout and
	nautilus_icon_container_is_auto_layout. For now they are
	placeholders that just modify a boolean.

	* nautilus-icon-private.h:
	Added the auto_layout boolean.

	* nautilus-icon-text-item.c:
	* nautilus-icon-text-item.h:
	Just some formatting and other minor cleanup.

	* nautilus-metadata.h:
	Added NAUTILUS_METADATA_KEY_ICON_VIEW_AUTO_LAYOUT.

	* nautilus-location-bar.c (drag_data_received_cb): Use the new
	nautilus_g_list_more_than_one_item function.

	* fm-directory-view.c (bonobo_menu_open_cb), (open_cb): Use the
	new nautilus_g_list_exactly_one_item.

	* fm-icon-text-window.c (attribute_names_string_is_good),
	(set_preference_string), (synch_menus_with_preference),
	(preference_changed_callback),
	(changed_attributes_option_menu_cb): Got rid of the hard-coded
	first item "name" which is no longer needed.  Also changed to
	handle bad data in the preferences.

	* fm-icon-view.c (fm_icon_view_initialize_class): Updated since
	there's no "name" item needed any more.
	(fm_icon_view_compute_menu_item_info): Merged MENU_PATH_RENAME
	with MENU_RENAME_TEXT and simplified the logic.
	(fm_icon_view_append_selection_context_menu_items): Merged
	MENU_PATH_RENAME with MENU_RENAME_TEXT.
	(update_layout_menus), (auto_layout_callback),
	(manual_layout_callback), (fm_icon_view_merge_menus): Added menu
	items for auto layout and for manual layout.
	(fm_icon_view_begin_loading): Load setting for auto layout from
	metadata.
	(fm_icon_view_get_icon_text_attribute_names): Changed to get rid
	of the "name" first item from the list of text attributes.
	(get_icon_editable_text_callback): Simplified since the editable text
	is always the icon name. Also got rid of copied and pasted code that's
	no longer needed for this case.
	(get_icon_additional_text_callback): Got rid of special case for name,
	since the name is no longer treated as an attribute.
