* Only allow small clock skews after the first 10 minutes of operation
      (to prevent later network lag bouncing us way off course - yes, we
      really need an NTP impl to balance out the network burps...)
    * Revamp the I2PTunnel web interface startup process so that everything
      is shown immediately, so that different pieces hanging don't hang
      the rest, and other minor bugfixes.
    * Take note of SAM startup error (in case you're already running a SAM
      bridge...)
    * Increase the bandwidth limiter burst values available to 10-60s (or
      whatever is placed in /configadvanced.jsp, of course)
