add cron registration status updates for Android devices #13

It would be good to query C2DM and GCM for accurate registered/unregistered status and provide that feedback to the sender if using an unregistered device and there is no new registration id in our registration table. Perhaps this could be done daily.

Linked to #12, but will probably be rolled out separately.

There is not a good 3rd party server status check for this like iOS, so for now we can mark registrations inactive when a message has not been received in over several weeks.
