Title: Adding classname aliases to prevent conflicts

Model\NotificationEventManager was conflicting with Entity\NotificiationEventManager when building the bootstrap cache.

$ php app/console cache:clear

This only seems to happen when building a new bootstrap cache. I suspect because in the process of building the bootstrap the Entity\NotificationEventManager was being loaded sometime before the Entity\NotificationEventListener is loaded, at which point 'using' the Model\NotificationEventManager brings it within the Entity\ namespace, causing the conflict.

Adding the alias resolves the error.
