I also have mixed feeling about it. First I wanted to create another instance of config in the `Boot` object, but then decided, that it probably would be "nicer" to have this logic in one place. But yeah... I mixed two very different things in this line.

I have not spent too much time here, but config probably can be retrieved from the actor system itself (akka uses the same config anyway) so it can be used on both sides (in the actor's cake and `Boot`).
