presence for cloud server friends #2297

A simple approach would be to periodically "ping" each cloud friend by SSHing into it and running zork's ping command.

I would hate to spend at this if we end up moving cloud servers to Quiver, though.

This was mostly done in #2798 - we now assume all servers are initially offline, then change them to online once they respond to a ping (TCP socket connection to the SSH Port 5000). However we don't detect if they go offline again - the only way a server will transition from online to offline is if the user restarts the app or browser.
