Allow for enabling Event Type Name in to 'From' instead of 'Subject'

In JIRA 4.4 the notification templates has changed(see JRA-12640) including the action performed on the sender (from field)(see attachment notification_jira_44.jpg), which was located on the notification subject in previous versions (see attachment notification_jira_43.jpg).

I raised this new feature to turn "action at the sender ('from' field) optional", where the customer can choose which whether to enable this change or leave it, as it better fits to his business needs.

Workaround for Subjects:
