Major code improvement under way

Today, a rails sensei pointed me to better way of coding, and Bloglation will be going through some serious code improvement. However, you should be able to continue to use it meanwhile.

There are also a couple of features that are added.

1. Ability to scrape Paul Graham's essays. He doesn't follow web standards, and thus Hpricot isn't able to extract information easily (like using
   
   for new paragraph instead of wrapping it with
   tags). I had to implement special hack just for Paul.
   
2. DB indexes and HTTP caching. In alpha stage, I don't know how much it would matter, but I am preparing for happy problems.
