Title: Change lastUpdated to lastSent and lastReceived

lastUpdated wasn't used, and wasn't very useful as it was changed each time anything in the node changed (including internal information). lastSent and lastReceived allows determination of the health of the node by knowing when it was last heard, and when we last sent data to it.
