Redcloth upwards - Apr 2008 - 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 :-) Some really significant improvement there!
