Stateful Token Authentication

Create a tokens table in the database with two columns:
- token text field, primary key
- user_id foreign key to the users table
In the POST /login request handler, after checking the user name and the password, generate a new token. It can be done using the uuid Node module (https://github.com/uuidjs/uuid). The token will look something like 1b9d6bcd-bbfd-4b2d-9b5d-ab8dfbbd4bed.
Insert the new token into the tokens table.
