This should eliminate page freezes when loading big files/diff. `highlightBlock` is needed to preserve existing nodes when highlighting and for that, highlight.js needs access to the DOM API so I added a DOM implementation to make it work, which adds around 300kB to the output file size of the lazy-loaded `highlight.js`.
