* libnautilus/nautilus-bonobo-ui.h:
	New file, contains #defines for Bonobo-style menu paths for all
	the menus & menu items in Nautilus that we promise components
	will exist.
	* libnautilus/Makefile.am: Include this new header file in library.

	* src/nautilus-window-menus.c: Extensive changes, too many to list
	every function. Replaced all the GnomeUIInfo mechanism with
	Bonobo-style menu creation, using the menu paths from
	nautilus-bonobo-ui.h. While I was in here, I also renamed some
	functions (especially xxx_cb -> xxx_callback), tweaked some text,
	and used some more standard Gnome menu item pixmaps (not sure if I
	like them or not yet).

	* src/ntl-window-private.h,
	* src/ntl-window.c:
	(nautilus_window_back_cb), (nautilus_window_forward_cb),
	(nautilus_window_up_cb), (nautilus_window_home_cb): Replaced
	these GtkWidget-callback style functions (formerly used
	by both menu items and toolbar buttons) with new NautilusWindow
	oriented ones nautilus_window_go_back, nautilus_window_go_forward,
	nautilus_window_go_up, and nautilus_window_go_home.
	(nautilus_window_allow_back), (nautilus_window_allow_forward),
	(nautilus_window_allow_up): replaced hardwired Bonobo menu paths
	with the new #defines.

	* src/nautilus-window-toolbars.c:
	Renamed some functions xxx_cb -> xxx_callback.
	(toolbar_back_callback), (toolbar_forward_callback),
	(toolbar_up_callback), (toolbar_home_callback): New GtkWidget-callback
	style functions used exclusively by the toolbar.

	* src/file-manager/fm-directory-view.h:
	Removed FM_DIRECTORY_VIEW_PATH_CLOSE and
	FM_DIRECTORY_VIEW_PATH_SELECT_ALL, since callers should use
	the paths defined by Nautilus for these.

	* src/file-manager/fm-directory-view.c:
	(fm_directory_view_real_merge_menus): Replaced special insider knowledge
	of menu positions with use of the new #defines. Also tweaked with the
	keyboard underscore shortcuts for some items.
