- Move BWLimits and DestLookup message support from
        I2PSimpleSession to I2PSessionImpl
      - Include the Hash in the DestReplyMessage on a failed lookup
        so the client may correlate replies
      - Add support for parallel lookups and BWLimits requests
      - Add support for specifying the timeout for DestLookups
        (can only be smaller than the router timeout for now)
      - Extend dest lookup router timeout from 10s to 15s

      - Change the UpdateHandler to try all sources in a loop, rather than one,
        so the user need not retry manually
      - For each source, fetch the first 56 bytes and check the version
        before downloading the whole thing, so we need not wait for every
        host to have the latest before updating the news.

                   tens of thousands of them

      - Add form for I2CP options
