created a hidden homepage

I made a page that is only accessible by those who are logged in. This will allow us to test log in.
Messed up the before_filter.

Now correctly does the redirect.
Added User creation logic.

Registration now works with User creation logic.
added the debugger to the Gemfile
added route aliases for sessions, and users.
cleaned up with form_tag over form_for
moved homepage to the correct language.
fixed the indentation on sessions_controller

I also finished up more of the login logic.
added :user_id to sessions now work
Modeled the interface for interacting with the User.

This is a first pass at an interface for Users, so we can change the implementation details for both passwords, and emails.
