	* app/display/gimpdisplayshell.[ch]: keep a pointer to the
	nav_ebox in the GimpDisplayShell struct.

	* app/display/gimpdisplayshell-handlers.c: connect to
	notify::navigation-preview-size and set the button insensitive for
	GIMP_PREVIEW_SIZE_NONE. Also destroy an existing nav_popup so it
	will be automatically re-created on the next click.  Connect to
	notify::image-title-format and notify::image-status-format and
	update them accordingly.

	* app/display/gimpnavigationview.c: don't try any voodoo in
	gimp_navigation_view_init(). Removed the notify handler.
	Set the popup's size in gimp_navigation_view_new_private().

	* app/gui/preferences-dialog.c: removed the #if 0'ed combo boxes
	and added an own sub-page for the image title and status format.
	Select the possible values using a GtkTreeView.  Some more
	cleanup.
