Update client to detect errors. The client doesn't treat non-200 responses as errors automatically, so we need to detect when the response.Errors property is set, and use that to return an error. To avoid the boilerplate and an extensive error system, I just wrapped them in an httpErrors type that implements the error interface. That way the errors can be returned, and callers can type-cast and interrogate them. I also updated the GetLogin function to return an auth.ErrLoginNotFound error when the httpErrors response indicates that's the reason the request failed.
