Needed to add content type to run in Chrome

[RomSocial]

Hi,

I would like to note that Chrome, running twitterwall by @remy complained about content type, so needed to add a line for it in server.js:

app.use(function(req, res, next) {
res.header("Access-Control-Allow-Origin", "*");
res.header('Access-Control-Allow-Methods', 'GET,PUT,POST,DELETE');
res.header("Access-Control-Allow-Headers", "X-Requested-With");
res.header('Content-Type', 'application/javascript');
if (req.method === 'OPTIONS') return res.send(200);
next();
});

Otherwis works great!
