    dir-spec: The ns consensus isn't explicitly ns
    
    tor does not generate ns consensuses that are explicitly labelled as ns
    consensuses. This updates the spec to make the flavor portion optional,
    and to allow the assumption to be made that if a flavor is omitted from
    the "network-status-version" line then it is "ns".
    
    One "flavour" was also turned into a "flavor" for consistency.
