Multiplex AJAX calls to /notification/individual/ through the JX.Leader so that there is a single request for each notification (instead of one request per client)
Currently, the Aphlict Server only makes clients aware of notifications. The client then makes an AJAX call to /notification/individual/ to retrieve the actual contents of the notification.
It would be better to have the Aphlict Server transmit the contents of the notification directly. This would require authentication between the client and server, which may be complicated.
