Change the Email Notifier Adapter to send notifications of cleared events

By default, the Email Notifier Adapter does not send messages when a notification clears. It only sends messages for new notifications or when the certainty of the notification changes.

To enable the Email Notifier Adapter to send CLEAR notifications, change the following in the file, BASEDIR/rules/notifier/mail/mail-filter.asl:

START () {
     OMIT_CLEAR_EVENTS
}

to

START () {
//   OMIT_CLEAR_EVENTS
}

After making changes to the file, restart the adapter for the changes to take effect.
