#### 2.0.0

- NOTE: This version includes breaking changes.
- Change params and credentials parsing
  This changes the signatures for request() and all crud methods:
    request(method, url, credentials, params, headers)
      => request(method, url, params: {}, headers: {}, credentials: {})
    all(), find(), create(), update(), delete(), etc
      => pass credentials: {} instead of the final api_creds param
- find(nil) now raises RecordNotFound instead of returning nil
- Make <:assoc>_id=() writers private; shouldn't have been exposed to begin with.
- Treat 409 like 422 and add error messages instead of raising an exception.
- Add default error message for 409,422 if none received.
- Make MultiJson optional - use it if present, otherwise default to stdlib JSON.
  If using MultiJson, requires v1.9+.
- Improve header handling for requests
- Add #update!(), #delete!()
- Add AccountInactive exception for 402 errors
