hacky use of setTimeouts to draw sensitive items after CSS loaded

@nicolashery Will you take a look at this? This is the only hack I could work out for fixing the late injection of the CSS problem... I tried the `ExtractTextPlugin` (as described [here](http://webpack.github.io/docs/stylesheets.html#separate-css-bundle)) first, but it didn't fix the issue. It did work in terms of building a separate CSS bundle (which I included via a `<link>` in the example index.html `<head>`, but the issue remained, not sure why since this problem did not arise using the combo of browserify and less to build an example.css and a bundle.js.
