$fh.sec api returns reversed objects

Issue

Currently, the policy of returning objects from mBaaS API calls is to return them in order of err, result. At the moment, $fh.sec returns them in the other way around. i.e. the docs for $fh.sec give an example where (err, result) is returned ...

$fh.sec({
  "act": 'encrypt',
  "params": {
    "algorithm": "AES", // mode : CBC, padding: PKCS#5
    "plaintext": "Need more starting pages",
    "key": secretkey,
    "iv": iv
  }
}, function (err, result) {
  if (err) {
    return console.log("Encryption failed: " + err);
  }
  return console.log("Encrypted data is " + result.ciphertext);
});

... where in actual fact it is (result,err) ...

$fh.sec({
  "act": 'encrypt',
  "params": {
    "algorithm": "AES", // mode : CBC, padding: PKCS#5
    "plaintext": "Need more starting pages",
    "key": secretkey,
    "iv": iv
  }
}, function (result, err) {
  if (err) {
    return console.log("Encryption failed: " + err);
  }
  return console.log("Encrypted data is " + result.ciphertext);
});

This results in the error object being populated even for a successful call so it appears to return an error.
