Title: Implement R language highlighter

Thanks for all of the feedback, hopefully this covers it all.

It is quite possible in R for lines to begin with numeric literals, so I had to include another copy of the number rules (but preprended with ^) in the default mode. Let me know if there is a better way to do this.
