user data adds on first time login

[KeithRWalker]

• Added a way to add the user data based off the info given from firebase/google auth. It happens in auth.js, and userData.js

• If you log out, and back in, or refresh the page you should see a console.error('new user added'), and if you log in again you should see another stating that the user is already registered.

• right now the data that gets uploaded to firebase is on the user node, and has a collection of unique ID's, and inside those nodes are the keys of

  displayName: "Full Name",
  email: "example@email.com",
  uid: "uid based on your id given by firebase"

We can go, and modify things a bit to add a custom user name, or separate first/last name in the future if needed, but as of right now everyone should have access to loop through each user, and grab their uid.
