* Disable the message history log file by default (duh - feel free to
      delete messageHistory.txt after upgrading.  thanks deathfatty!)
    * Limit the size of the inbound tunnel build request queue so we don't
      get an insane backlog of requests that we're bound to reject, and adjust
      the queue processing so we keep on churning through them when we've got
      a backlog.
    * Small fixes for the multiuser syndie operation (thanks Complication!)
    * Renamed modified PRNG classes that were imported from gnu-crypto so we
      don't conflict with JVMs using that as a JCE provider (thanks blx!)
