* Stats:

      - Fix BufferedStatsLog so it works at all
      - Don't instantiate BufferedStatsLog unless stats.logFilters
        property is defined (restart now required to enable logging)
        This eliminates the StatLogWriter thread and a decent
        amount of memory.
      - Move two CLI classes out of the lib
      - Commment out places where getStatLog() isn't checked for null
      - Cleanups
