Token status notification

The token status notification is not set up by default, but can be configured by the user. There are 3 different events that will trigger this type of notification. These events are:

1. A new token is created and the status has been set as active.
2. An existing token has had its status changed: from active to disabled.
3. An existing token has had its status changed: from disabled to active.

When the conditions of an event have been met, all users that have been subscribed to the notification will receive an email notifying them of the change.
