Subject: Add a few more methods for future introspection to the Router.

The HasPath method check if a path is know by the router and return a
boolean.

The RemovePath method is useful to remove dynamically a path from the
router.

The GetAllRoutesByMethods returns a list of routes that match a given
method.

I'm not sure I'll keep all those methods available since there's no
immutability on the routes, and I don't want the user to mess with
them.  We will see later.
