Title: Removed error_format, will match the request content-type matched format.

See the discussion in https://github.com/intridea/grape/pull/282.

This removes `error_format`. It's confusing to expect JSON as a response, but get an error in txt format. With this change that is no longer possible, and the error format is matched the same way as the response format.
