Create a signup button to allow for a registration workflow, as opposed to purely "login".

[JohnVonNeumann]

Is your feature request related to a problem? Please describe.
Currently, we only have a login button available to users, and this only allows for one auth flow, working off the assumption that the user already exists within the application.

Describe the solution you'd like
We need to create a separate signup button that allows new users to register for the service, and points them directly to new user signup via Auth0.

Describe alternatives you've considered
Leave it, just let users use the login button and find their way to the signup themselves.
