Bug 1372536: Add a separate function to PluginArtefact, PluginInteraction and
PluginModule that lets you add menu entries especially to the right nav menu,
including top level entries.
The method right_nav in web.php still includes elements from the old menu_items
function for backwards compatibility but ignores all top level entries.
