Close browser window after sign in

[scriptPilot]

After sign in, the browser window should redirect to the local server and should be closed automatically.

I helped myself by modifying the LoopbackRedirectServer.js file:

if (req.url && url.parse(req.url).pathname === callbackPath) {                  

    // Show message after sign in instead of forwarding to another website
    res.end('Google sign in successful. You can close this browser window.')
    /*
    res.writeHead(302, {
        Location: successRedirectURL,
    });
    res.end();
    */

    resolve(url.resolve(`http://127.0.0.1:${port}`, req.url));
    this._server.close();
}

While we are on electron there is no necessity on redirecting to other website. So I am creating a pull request to add this feature.
