I tried moving both `highlight.js` and `marked.js` to [`main.js`](https://github.com/cvan/galaxy/blob/master/src/media/js/main.js#L5-L16), however it thought that [`hlrs`](https://github.com/cvan/galaxy/blob/1f8f811d0fe8105b24282df4a4ab122f9fab5b65/src/media/js/lib/marked.js#L1232) was not defined.
