Benchmarking, performance tweaks

Hey, I did some benchmarking of RedCloth and changed the Ragel code
generation style to one that will use 14.6 MB of memory when you
compile rather than the 391MB it was using before. It compiles
faster and the compiled file is smaller now too (about 223K). A nice
milestone as we commit revision [300]!

Great work :slight_smile: Some really significant improvement there!
