I added two new features to the lock-loss-alerting system today.

Guardian repeat alerts

Guardian alerts are now handled the same way as lock-loss and out-of-observation alerts. The user has the option for a single alert (default time is immediate) or single alert plus repeat alerts (see attachment).

GraceDb event time

The time of the GraceDb event is shown both as its GPS time and a more readable time string like '50 minutes ago' or '5 hours ago' (see attachment)
