Error object spec non-compliance

[ssimeonov]

The response parsing code in https://github.com/movitto/rjr/blob/master/lib/rjr/messages/response.rb#L73 expects that error.class is available in the case of error responses. The spec mandates that any additional error information is kept in error.data.

Ah good catch, hadn't realized that. We could leave error_class as is though as a RJR-specific thing, such as w/ the generic json-rpc headers, allowing the client to specify the contents of error_data when appropriate. Or could just simplify it and use error_data to store the class (and remove the later).

Am fine w/ either, will create an issue to keep track of the change.
