BREAKING CHANGE: The `Url` type is no longer used. Any instance in the `Client` API has had it replaced with `hyper::Uri`. This also means `Error::Uri` has changed types to `hyper::error::UriError`. The type `hyper::header::parsing::HTTP_VALUE` has been made private, as an implementation detail. The function `http_percent_encoding` should be used instead.
