* Delay shitlist cleaner at startup
    * Strip wrapper properties from client config
    * Define multiple cert type
    * Prohibit negative maxSends in streaming
    * HTML fixup on configtunnels.jsp
    * Increase wrapper exit timeout from default 15s to 30s

   - 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

      - Add i2cp.gzip option (default true)
      - Don't bother compressing if really small

      when the initial data is larger than one MTU,
      e.g. HTTP GETs with large URLs, CGI params or cookies,
      or large HTTP POSTS:
      - Don't reject additional packets received without a
        send stream ID (i.e. sent before the SYN ACK was received)
      - Put unknown non-SYN packets on the SYN queue also
        so they won't be rejected
      - Reduce flusher delay to 250ms (was 500)
      - Flush unless window is full (was window is non-empty)

      - Add a signed Certificate type
      - Add a main() to PrivateKeyFile to generate
        Destinations with various Certificate types
      - Add a VerifiedDestination class to check Certificates
        of various types
      - Add a HashCash library from http://www.nettgryppa.com/code/
        (no distribution restrictions)
      - Allow non-null Certificates in addressbook

    * i2psnark: Add codevoid link, remove mastertracker
    * hosts.txt: add echelon, codevoid

    * configpeer.jsp: Add blocklist info
    * help.jsp: Add link to German FAQ
    * tunnels.jsp: Fix inactive participating count

      code from 3 checkins ago
    * tunnels.jsp: Sort participating tunnels by usage, display rate

    * Tunnels:
      - Add missing message accounting for inbound gateways,
        we were underestimating participating traffic because of it,
        and the tunnels were classified "inactive"
      - Add participating tunnel role on tunnels.jsp

      - Correctly check inbound and outbound total bw limits separately
      - Fix up and actually use the tunnel.participatingMessageCount stat,
        favor it if lower than the total bw stat, so that
        client traffic isn't included for throttle decisions
      - Reduce min message count from 60 to 40
    * Tunnel Dispatcher:
      - Add tunnel.participatingBandwidth stat
      - Remove all 3h and 24h stats

    * configlogging.jsp: Increase box width

    * NetDb: Add netDb.exploreKeySet stat
    * netdb.jsp: Add parameter ?r=xxxxxx to view a single routerinfo,
      and ?r=. to view our own; change links on other pages too

    * UpdateHandler: Cleanup, clarify failure message

    * Tunnel BuildExecutor: Debug cleanup

      peer for direct RouterInfo stores, to mimimize floodfill
      connections
    * Peer Profiles: Classify connected peers as "active",
      which will help improve the fast pool
    * Transport Manager: Add isEstablished(Hash)

      so floodfill routers don't get backed up

    * NTCP: Add connection limit, set by i2np.ntcp.maxConnections,
      default is 500 (very high for now)

      (thanks devzero!)

      - Avoid peers whose netdb is old, or have a recent failed store,
        or are forever-shitlisted
