(no, this doesnt fix things yet, but its a save point along the path)

    * Rather than the fixed resend timeout floor (10s), use 10s+RTT as the
      minimum (increased on resends as before, of course).
    * Always prod the clock update listeners, even if just to tell them that
      the time hasn't changed much.
    * Added support for explicit peer selection for individual tunnel pools,
      which will be useful in debugging but not recommended for use by normal
      end users.
    * More aggressively search for the next hop's routerInfo on tunnel join.
    * Give messages received via inbound tunnels that are bound to remote
      locations sufficient time (taking into account clock skew).
    * Give alternate direct send messages sufficient time (10s min, not 5s)
    * Always give the end to end data message the explicit timeout (though the
      old default was sufficient before)
    * No need to give end to end messages an insane expiration (+2m), as we
      are already handling skew on the receiving side.
    * Don't complain too loudly about expired TunnelCreateMessages (at least,
      not until after all those 0.5 and 0.5.0.1 users upgrade ;)
    * Properly keep the sendBps stat
    * When running the router with router.keepHistory=true, log more data to
      messageHistory.txt
    * Logging updates
    * Minor formatting updates
