Views are pretty much done style-wise.

The login functionality still seems to pass user and password in URL parameters after logging in. That's something that should change, even if we encrypt passwords.

The logout logic is very simple and simply sets the session[:user] to nil in the login controller.

Some currently absent functionality:

- Going back to the decks list from the deck (nonplural) page.

- Storing/displaying guess history

- Allowing a user to retry unanswered/incorrectly answered cards from a deck.
