Title: Router.navigate should optionally fire also with same fragment

I found this useful when route callback is a GET remote request.
An alternative could be to fire the callback directly but since _extractParameters is very smart & useful to decode parameters, reimplementing the parsing & decoding logic elsewhere could be considered wasteful.
