Required bootstrap in the JS, woo
included the SessionsHelper, so the controllers also have access to the joys of the current_user, etc
Added sign_in user method to 'create' action, so that sessions generate cookies and are permanent (ie, they actually work!)
Added remember_token and related methods to the User model
Built in a lot of extra navigation into the header partial
Added test for remember_token, woo
Created SessionHelper module, in order to have critical session methods available to both the view and controller.

Chucked a remember_token field into the User table in the DB, so that the backend can figure out if there is a legit user based on their cookie.
Hunted for a typo (turned out to be an unnecessary '@' symbol) that was wrecking sessions

Gutted some other typos as well (and added some unnecessary code to the app controller)
Cut out some unnecessary code
