User authentication groundwork

[benzend]

Need to be able to authorize users throughout the application before we're able to give them access.

Thinking that we're going to need to keep a couple of things in mind:

• Certain areas in the application being accessible by everyone. (e.g. sign in, sign up, shareable states)
• A secure system of user authorization (JWT)

Added in JWT. Still need to do further validation checking and finish setting up database quires.

I think we're super close if not already there. It looks like the user keeps the cookie from the backend so I might not need to manage auth as much in the frontend which is awesome!
