     shutdown the whole router when ooming.

   - Better handling of 504 gateway timeout
     (keep going up to limit of retry count rather
      than just one more partial fetch)
   - Add -t cmd line option for timeout
   - Better handling of 403, 409, 503 errors
   - Don't keep going after unknown return code
   - Don't delay before exiting after a failure

    - 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

    - Use new I2PAppThread that does not call global listeners on OOM,
      so that OOMing apps will not shutdown the whole router.
