    * Only build new extra tunnels on failure if we don't have enough
    * Fix a fencepost in the tunnel building so that e.g. a variance of
      2 means +/- 2, not +/- 1 (thanks dm!)
    * Avoid an NPE on client disconnect
    * Never select a shitlisted peer to participate in a tunnel
    * Have netDb store messages timeout after 10s, not the full 60s (duh)
    * Keep session tags around for a little longer, just in case (grr)
    * Cleaned up some closing event issues on the streaming lib
    * Stop bundling the jetty 5.1.2 and updated wrapper.config in the update
      so that 0.4.* users will need to do a clean install, but we don't need
      to shove an additional 2MB in each update to those already on 0.5.
    * Imported the susimail css (oops, thanks susi!)
