* updated stats:

- sendsPerFailure: how many partial sends we make when they all fail
- timeoutCongestionInbound: describes how much faster than our average speed we were receiving data when each partial send timed out (in Bps)
- timeoutCongestionMessage: our send processing time when each partial send timed out (in ms)
- timeoutCongestionTunnel: our tunnel test time when each partial send timed out (in ms)
- participatingMessagesProcessedActive: # of messages more than the (most recent) average that a tunnel we were participating in transmitted (for tunnels with more than the average)
* updated to use Writer for rendering the console, so we can do partial writes (and hopefully help debug some kooky threading bugs on kaffe)
