	* libnautilus-extensions/nautilus-user-level-manager.h:
	Retire.  No longer needed.  User level things are handled in
	nautilus-preferences.[ch] now.  The current user level design is
	much simpler and does no require its own GtkObject.

	* src/file-manager/fm-desktop-icon-view.c:
	(update_home_link_and_delete_copies), (real_update_menus):
	* src/file-manager/fm-directory-view.c: (open_location),

	* src/nautilus-switchable-search-bar.c:
	(nautilus_switchable_search_bar_new),
	(nautilus_search_uri_to_search_bar_mode):
	Update for preferences api changes.

	* src/nautilus-window-manage-views.c:
	(position_and_show_window_callback),
	(nautilus_window_end_location_change_callback):
	Update for preferences api changes.  Also, no longer need to pass
	in a default location to the preferences getter.

	* src/nautilus-window-menus.c: (user_level_customize_callback),
	(switch_to_user_level), (refresh_bookmarks_menu),
	(user_level_changed_callback), (add_user_level_menu_item),
	(nautilus_window_initialize_menus), (update_user_level_menu_items),
	(convert_user_level_to_path):
	A lot of simplification.  The "Edit Settings..." menu item no
	longer changes it wording based on the user level.  We know allow
	it to edit settings on all user levels, since we have the ability
	to hide preferences at higher user levels.  No longer need to
	update the preferences dialog or its title.

	* src/nautilus-window.c: (nautilus_window_constructed),
	(nautilus_window_close), (nautilus_window_go_web_search),
	(nautilus_window_go_home), (nautilus_window_show):
	Update for preferences api changes.

	* libnautilus-extensions/nautilus-global-preferences.h:
	Update all the preferences defines to not include a full gconf
	path.  We dont need to do this anymore to get non user level
	coupled prefernces.

	* libnautilus-extensions/nautilus-global-preferences.c:
	(compare_view_identifiers), (global_preferences_create_dialog),
	(nautilus_global_preferences_get_enabled_sidebar_panel_view_identif

	(register_proxy_preferences), (global_preferences_register),
	(global_preferences_install_defaults),
	(nautilus_global_preferences_set_dialog_title):
	Lots of changes to support new preferences design.

	Set the WM_CLASS here once instead of everytime the dialog title
	is changed.  This was causing criticals.

	No longer need to create parallel proxy preferences and map them
	to the gconf ones.  We can use the gconf ones directly now.
