#645 Allow an object to be attached to an alarm event.

[Rick McGuire]

The new alarm notification event passes the alarm object to the notification object when it is triggered. It would be useful if an arbitrary object can be attached to the alarm that can be retrieved in the event handler. This would be very useful for scheduling events.
