still required router-deprecated

[dsoltesz]

Why does the latest primeNG need @angular/router-deprecated to be defined in packages and registered in systemJs in order to use the primeNG components?

Some components use it e.g. splitbutton and menus. We don't suggest the new router yet as it is undocumented and have some issues. We'll update to new router once it gets stabilized hopefully in next Angular RC release. So sticking to the beta router for now.
