	Changed menubar showing/hiding to work like rulers and statusbar:

	* app/config/gimpconfig-blurbs.h
	* app/config/gimpdisplayconfig.[ch]: renamed "menu_bar_per_display"
	to "show_menubar". Removed GIMP_PARAM_RESTART flag.

	* app/display/gimpdisplayshell.[ch]: chaged shell->item_factory to
	shell->menubar_factory plus shell->popup_factory and always create
	both of them. Added "gboolean update_popup" to
	gimp_display_shell_set_menu_sensitivity() and call it recursively
	with update_popup == TRUE if the display it is called for is the
	active one.

	* app/display/gimpdisplay.c
	* app/display/gimpdisplayshell-callbacks.c: changed accordinly.

	* app/gui/gui.c: ditto. Set the menu sensitivity of new displays.

	* app/gui/menus.c: added "<Image>/View/Toggle Menubar" menu item.
	Moved some factory initialization code from gimpdisplayshell.c
	here.

	* app/gui/view-commands.[ch]: added
	view_toggle_menubar_cmd_callback(). Update the menu sensitivity
	manually in all callbacks which don't call gimp_image_flush().

	* app/gui/preferences-dialog.c (prefs_dialog_new): moved the "Show
	Menubar" toggle to the "Appearance" frame of the "Image Windows"
	page. Added an own frame for the display zoom/scaling settings.

	(preferences_dialog_create): Attach config_copy and config_orig
	using g_object_set_data_full() instead of just g_object_set_data()
	plus a g_object_weak_ref().

	(prefs_default_resolution_callback): set the resolution for both
	fields of the "size_sizeentry" instead of setting it for "x"
	twice.
