From 2965a788cfcf4a0386cb8832e0d96491bf54c1d3 Mon Sep 17 00:00:00 2001

Subject: Display a different / page depending on whether the current identity
 is valid or not.

This is mostly a proof of concept for the implementation of form login implemented in previous commits, but it _is_ useful as it controls whether the / page shows login, or shows logout.

From here, chat is next!
