Can't have a route run on all pages

Example: https://github.com/OscarGodson/todomvc/blob/5666d87f4ec7671008d01e7c426fce80b0faeff2/vanilla-examples/vanillajs/js/controller.js#L33-L38

I would have liked to do a * and it would have run on all pages. Problem is that it overwrites other handlers.

Like this:

router.on('*', function () {
  this._updateFilterState();
});

You can specify an on member of the object passed to Router.configure that will run on all routes.

It would be fantastic if multiple route handlers that matched the same string would each run, though!
