Add the ability to Copy in Notification Manager

D128: As a user, I'd like to copy things in the Notification Manager.
•Provide a way to copy the items in a group of triggers to another group of triggers.
•Provide a way to copy all triggers with notifications to another group - this does copy the group items.
•Provide a way to copy some or all notifications from one trigger to another trigger
•Provide a way to specify the same triggers (2 job fail) into a group and in each trigger can have different definitions (currenlty doesn't allow duplicate triggers).
•Provide a way to define a notification (e.g. Email) once and have it populate on all selected triggers.
