Allow users to set their email notification preferences
Currently, when email notifications are enabled, all Zephyr users receive all available notification emails automatically. As a user, I'd like the ability to set my own preferences to receive only the notifications I care about. For example, I may want to receive a notification only when a test case is assigned to me and not receive any emails when a test case is moved or modified, etc. OLD ID:- ZENT-I-120
