RubyGems 0.8.8 with better dependency management

I forgot to mention that a new and much improved version of RubyGems was made available a while back. The new version makes it a lot easier to install Rails with all of the dependencies thanks to the added --include-dependencies option and you can cleanup older versions of Rails with the new cleanup command.

The RubyGems team also started using Hieraki to do documentation. Checkout RubyGems Manuals.
