* [Notifications] Added timestamp and object name to copy notifications \n
-Fixes issue #331
-Added timestamps to all notifications
-Added object name to copy success notification
-Updated placement and style of notification timestamp as discussed with Charles.
New test suite for the notification service covering common use cases. Fixed the bug where autoDismiss would be set wrong for info notifications; also treating info notifications appropriately now.
In the spec: NotificationService knows about concepts like "info", "alert" and "error" only, having a plain info notification model called successModel doesn't help much and may be confusing at times (makes you think it's something the service treats separately).
