    Tag NetworkManager to 1.18.0
    
    NM's repository started including dependencies without using Git sub
    modules, which means it's essentially not buildable in the Continuous
    sandbox.
    
    Thus begins the attempt at finding a recent enough tag that lets us
    build NetworkManager.
