- Don't create SnarkManager instance until first call,
      so it doesn't create the i2psnark dir, read the config,
      etc., for single Snark instances.
    - Don't read i2psnark.config twice; fix setting
      i2psnark.dir
    - More Snark constructor changes for calling from router
    - Make max connections per torrent configurable
