Enable Push Messaging

Use Chrome's implementation of PushMessagingService. This feature
relies on notification permissions, so it is not different from
Web Notification from end-users perspective.

We don't persist push subscriptions, because it seems these have
to be consistent with persisting notification permissions.

Make address of push service configurable by a profile setting.
It is empty by default - which means the feature is disabled until
the user sets the address of a push service.
