Convert RWO automatically

[rickyvetter]

Similar to OCaml documentation - lets do https://realworldocaml.org/ automatically so that learning Reason is painless.

I'd like to help, if I can.

@rcsole awesome! We basically need to add a content script to the manifest.json file which runs only on the realworldocaml.org domain.

Inside that script we need a converter similar to the ocamldoc one which will convert the code examples that RWO uses. The conversion can't just take the straight contents of the code block, because lots of the examples are actually interactive utop sessions and need to be translated line-by-line.

Let me know if you're able to work on this!
