Pass token on query string / allow passing custom getToken function

It would be nice to allow passing the token on the query string (?token=....) instead of having to passing it as a request header. express-jwt permits this by allowing you to pass a custom getToken function like so:

app.use(jwt({
  secret: 'hello world !',
  credentialsRequired: false,
  getToken: function fromHeaderOrQuerystring (req) {
    if (req.headers.authorization && req.headers.authorization.split(' ')[0] === 'Bearer') {
        return req.headers.authorization.split(' ')[1];
    } else if (req.query && req.query.token) {
      return req.query.token;
    }
    return null;
  }
}));

Thanks for the reminder, @nfantone 😃 I‘ve merged it and published 1.2.0.

Thanks for the contribution, @danwkennedy!

I’m gonna leave it. You could do something similar inside of the getToken function (i.e. check this or check that)
