Ensure we have JS/CSS built prior to serving locally.
  Added missing rewrite rules, for testing purposes.
  The /interest/ link should remember login-state.

  We didn't set the template parameter so all visits looked
 like anonymous ones.
  Reworded premium feature lists.
  Record username, for non-anonymous users.
  Allow the dump to be limited to IPv4 | IPv6
  Make all pimping of premium features conditional.

 of the DNS records.
