Steps to reproduce:

In order to add, update or remove habits the user must have an active Facebook session. Sessions in Habit Tracker are managed through the Node module Passport. If you are inactive for a while and visit the page on your phone, your session will have expired. However, unless you reload the page, you will still see your profile. In this state, AJAX requests will not succeed because the user lacks authorization.

Solution:

Use the Facebook JavaScript SDK to detect expired sessions and redirect the user to the /auth/facebook/ route, which will renew the session if the Passport session has expired.

Steps to reproduce:

1. Create a habit and level up to 3 or 4
2. Slack off in the habit until you are demoted to level 1
3. Mark the habit as complete
4. The habit go back to level 1 on its own after ~10 seconds

The "Sign up with Facebook" button should be smaller than the "Stick to good habits" tagline

Facebook IDs are parsed as floats before being stored in Dynamo. The length of the numeric ID surpasses the floating point precision limits of JavaScript. The ID needs to be treated as a string on the server, the client and in Dynamo.

It's possible to create a habit with a blank title and/or frequency. I believe this causes a clientside error that prevents other habits from being rendered. Ensure that validation for new habits prevents these blank values.
