Change $loop visibilty to allow inheritance use

[Maxooo]

It should be nice to have access to the loop variable in a child class that extends the Server one.

This can be achieved via constructor overloading without having to change the React code base:

class MyServer extends \React\Socket\Server {
    private $loop;

    public function __construct(\React\EventLoop\LoopInterface $loop) {
        $this->loop = $loop;
        parent::__construct($loop);
    }
}

@cboden First of all thank you for your quick answer. This is exactly what I''ve done, but it looks more like a workaround than a real solution. I mean, "protected" visibility exists to avoid this kind of practice and make life and coding easier =)
