Hello, can you add a function to support displaying line numbers?

Technically it should be able to do this with Prism. It's currently broken on my demo site for some reason. I am planning on doing some maintenance soon, I've just been busy and haven't had the time to get to it yet. Aside from that, line numbers would need to be something Prism or Highlight.js needs to support.

I'll keep this issue open for the time being until I can do the updates so I don't forget to make sure the Prism line numbers plugin works again.
