[FRONTEND] Display appropriate view on front page based on member role

Is your feature request related to a problem? Please describe.

Right now it always shows log-in and register even if the user is logged in

However there is another case where a user has not yet paid for membership but has an account. In that case we should keep the register button, but possibly change the text.

For users that have paid, none of these should be shown.

Admins should be able to see all just for completeness
