Migrate code

So I guess we need to migrate code into this repository and make it fit the new way of extending highlight.js.

The starting point, I guess, is the code here:
https://github.com/highlightjs/highlight.js/pull/1844

The endpoint should be something along the lines of what we can see here:
https://github.com/highlightjs/highlightjs-solidity

How do we organise this? Who takes a first stab at making it work?

Start by reading highlight.js pull request #1844 and the highlightjs-solidity repository linked in the issue. Compare how the existing code is organized with the newer extension approach, then define the migration structure and verify that Turtle and SPARQL highlighting works through the resulting repository integration.
