Implement "stats" page with server-side delay

[msgilligan]

Port stats.gtpl to Node.js. This means figuring out a way of forcing a two second delay before the page is returned.

@mikhailxu @truedat101 How can you easily and cleanly do a 2-second delay using Node.js (or connect, etc)

[truedat101]

For sure you can use set timeout().  For a node sleep, see answer http://stackoverflow.com/questions/13448374/how-to-sleep-the-thread-in-node-js-without-affecting-other-threads

I figured there would be a setTimeout(). But I don't know how to integrate that with Node page- or template-serving functions. I'm hoping for a pull-request :)
