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

      - New, disabled by default, except for blocking of
        forever-shitlisted peers. See source for instructions
        and file format.
    * Transport - Reject peers from inbound connections:
      - Check IP against blocklist
      - Check router hash against forever-shitlist, then block IP

        Don't proactively reconnect until 30m idle, so
        we don't lose introducer tags prematurely

      - Try to pick better introducers by checking shitlist,
        wasUnreachable list, failing list, and idle times
      - To keep introducer connections up and valid,
        periodically send a "ping" (a data packet with no data and no acks)
        to everybody that has been an introducer in the last two hours
      - Add a stat udp.receiveRelayRequestBadTag, make udp.receiveRelayRequest only for good ones
      - Remove some 60s and 5m stats, leave only the 10m ones
      - Narrow the range for the retransmit time after an allocation fail
      - Adjust some logging

      - Don't write router key backup when leaseSet keys are updated
      - Synchronize to prevent concurrent writes (thanks Galen!)
      - Backup keys every 7 days instead of every 5 minutes

      - Repair corrupted files with wrong length rather than die
      - Register shutdown hook to properly shutdown torrents when
        the router shuts down, hopefully will reduce corruption
      - Add Galen tracker
      - Add a note about how to chane directory

      - Try to fix 100% CPU, caused perhaps by JVM NIO bug...
      - Fix failsafe stats

      - Fix NPE caused by race (thanks echelon!)
      - Add mastertracker, remove de-ebook

      susidns, and susimail for use when the .wars are not running

     and '88d299913d4aeb0ef7e8adabb5c39255e9cca0d2'

    * Summary bar:
      - Display Warning for TCP private IP address
      - Display PRNG stats

    * Summary bar: Display helpful errror message when UDP bind fails
    * UDP: Don't bid when UDP bind fails
