Introducing F1 Authentication and Adding Site Content.

This change introduced the f1oauth and jesterpm oauth packages for
interacting with Fellowship One's developer API. I have also reworked
the login authentication to verify credentials through F1 and added
session management to track logged in users.

The Authenticator chain works as follows: on every page load we check
for a session cookie, if the cookie exists, the Request is marked as
authenticated and the OAuthUser object is restored in ClientInfo. If
this request is going to an account page, we require authentication. The
LoginFormAuthenticator checks if the user is already authenticated (via
cookie) and if not redirects the user to the login page. When the login
form is submitted, LoginFormAuthenticator catches the POST request and
authenticates the user through F1.

I'm also adding a new account page, but it is currently a work in
progress.

This commit also adds Allen's content to the site.
