* Improved the bandwidth throtting on tunnel participation, especially for
low bandwidth peers.
* Improved failure handling in SSU with proactive reestablishment of
failing idle peers, and rather than shitlisting a peer who failed too
much, drop the SSU session and allow a new attempt (which, if it fails,
will cause a shitlisting)
* Clarify the cause of the shitlist on the profiles page, and include
bandwidth limiter info at the bottom of the peers page.
* Added a small new page to the web console (/peers.jsp) which contains
the peer connection information. This will be cleaned up a lot more
before 0.6 is out, but its a start.
