    roomManager: add a way to track the first session
    
    The isFirstRun property tracks whether or not this is the
    first time polari is opened, and the isRoomAdded property
    tracks whether or not rooms have been joined this session.
    The prepare-shutdown signal is tracked in order to check
    if we should delete the file or not.
