Title: Implemented Application::onUpdate so that an application can push messages

I could not see any functionality which would allow one to perform operations/queries on every server tick and push to clients as needed.

A use case for this is if you want to create a notification system which, for example, checks if any new records have been added to a DB table and notifies clients of the change.

A sample application was also added (ServerTimeApplication) which pushes the server time to clients once per second.
