Refine the Auth0 login process

[Ezequiel-Valencia]

The new authentication method has been implemented within the Java client application, but it's rough around the edges.

• [x] Remove legacy login GUI and place it within the Web (need it on the web anyways, so why not only on the web)
• [x] There is no formal flow and GUI if you've forgotten your old VCell password
  • [x] Bring over lost password endpoint to the new API
• [ ] The legacy authentication code that is dead is still within the code base
• [x] Browser tabs that open but never close when performing authentication
• [x] Opt out of login (currently seems like you need to login to utilize VCell. There is an offline mode available)
  • [x] Don't want to surprise them with a browser, give some GUI that tells them
• [x] New users
  • [x] Prompted with webapp to create VCell user
  • [x] Automatically create VCell user from email
• [x] Social Login
• [ ] Authentication and refresh token stored in JSON locally
  • [ ] There's plenty of pro's and con's with this security, clients aren't fully trusted
