Subject: [PATCH] Mark old last_seen devices as "not responding"

Devices that have not received an update since a fixed timeout (24 hrs
for now), based on its last_seen time, will be marked as "not
responding" in the Home app. With this I can identify which devices are
unreachable or dead.

Also needed to upgrade hap with the fix for brutella/hap#30, or the
entire bridge will stop working.
