Subject: [PATCH] Extend RestException to also accept error object

This enables the developer to return additional data to user.
So in case of an error in REST, the error can be additionaly explained

{
  "error": {
    "code": 400,
    "message": "Missing properties",
    "data": {
      "severity": "high",
      "missing": [ 'date', 'name']
    }
  }
}
