Episode 7 - Cucumber, part 2

Continuing where we left off in part 1, we finish getting all our features to pass.

We cover:

• Refactoring the step definitions that are using have_tag to use XPath. At the time we were not aware that has_tag was renamed to has_selector in Rspec2.
• More capitalization issues with Capybara.
• Changing the way we access the currently logged in user from the step definitions, because Capybara no longer provides access into the controller the way Webrat did.
• We rip out the admin section. We are going to replace it with Typus at a later time.
