[GraphHopper] Incomplete routeing (@ Gates?)

We want to make sure the routes are really possible and so we avoid
routes with certain barriers.
But indeed there seems to be some inconsistencies for bike and foot.
E.g. for bike we disallow: kissing_gate, stile, turnstile
and for foot we are more restrictive (gate and swing_gate) which we
should rethink. Maybe you create an issue for this?

Peter.
