enhancement(realtime): send metadata update on revision save

Browse source 
When the frontend is notified about metadata updates, it refreshes the
data and therefore refreshes information like the timestamp of the last
revision save in the sidebar.
This commit adds such a notification from the backend to all clients on
each revision save, so that the "last saved at" value in the frontend is
correct.
