Update generated error classes to end with Response instead of Request
Use play.utils.UriEncoding.encodePathSegment to encode path segments.

java.net.URLEncoder.encode does not encode path parameters correctly, while
it is (mostly) sufficient for query parameters. Use a Play API call which
tries to do the right thing, see the API at
http://www.playframework.com/documentation/2.3.x/api/scala/index.html#play.utils.UriEncoding

Path segment encoding differs from encoding for other parts of a URI. For
example, the "&" character is permitted in a path segment, but has special
meaning in query parameters. On the other hand, the "/" character cannot appear
in a path segment, as it is the path delimiter, so it must be encoded as "%2F".
These are just two examples of the differences between path segment and query
string encoding; there are other differences too.
