Subject: [PATCH] Adapt the idle treatment from the answering phase to the
 judging phase

Big copy/paste here, (obviously it would be better to capture the
common code in a "phase" module of some sort).

Note that this is currently untested, only because we haven't gotten
the client listening for judging-idle yet.
