This resolves the above mentioned issue by adding a `RememberMeBadge` to `JsonLoginAuthenticator` and by extending `CheckRememberMeConditionsListener` to be able to read the remember me parameter from a JSON request body (if reading from ParameterBag was unsuccessful).

This means you can send a JSON request with a body like this and needn‘t use a fallback HTTP form login when building your API:

```json
{
    "username": "dunglas",
    "password": "MyPassword",
    "_remember_me": true
}
````
