  * Significantly refactor configuration handling
  ConfigFlags is not used in any of the modules that do the real work, instead
  we just pass in the necessary information. Renamed ConfigFlags to SavedConfig
  and moved it's definition into the Config module. Also change what information
  is kept in the Repo type so that it knows the local path too. A PkgInfo now
  also knows which Repo it is from.
