title: Register router directives globally with angular router rc3
body: <p>I do not want to register the Router_Directives for every component.</p>
  
  <p>I want to do it globally as I did before:</p>
  
  <pre><code>import { RouterConfig ,Router, ActivatedRoute, ROUTE_PROVIDERS} from '@angular/router';
  bootstrap(AppComponent, [APP_ROUTER_PROVIDERS, HTTP_PROVIDERS, ROUTE_PROVIDERS ]);
  </code></pre>
  
  <p>but ROUTE_PROVIDERS does not exist/exported in router module.</p>
  
  <p>How can I do that with the RC3 router?</p>
