Port Notification Action Triggers from DOJO to Angular.  This consists of 4 grids, each
navigated to by its corresponding tab. The Trigger Event Definitions grid allows
cloning of records. When cloning there is the option to clone environments.  When editing
 an event defintion one can also edit parameters, environments, and run tests.
