Add HTTPS Support

We may want TLS/SSL running on a different port.  If so, we simple add a config option for secure port, and create a new express server like
```javascript
var http = require('http'),
      redirectServer = express();

redirectServer.use(function (req, res) { res.redirect('https://localhost:' + cfg.securePort);
http.createServer(redirectServer).listen(cfg.port);
```
If cfg.securePort is `443`, all requests to `http://localhost:8080` are rerouted to `https://localhost:443`.
