Using new UserClass instances everywhere:

- No more direct access to g.current_user, unless unavoidable.
  - Using pillar.auth.current_user instead of g.current_user or
    flask_login.current_user.
  - p.a.current_user is never checked against None.
  - p.a.current_user.is_authenticated or is_anonymous is used, and never
    together with a negation (instead of 'not is_anon' use 'is_auth').
  - No more accessing current_user a a dict.
  - No more checks for admin role, use capability check instead.
