VERSION 0.8.1

This, quick on the heels of 0.8.0, fixes the fact that TCP tunneling was
broken. :)

There was a bug that only manifested in some cases, and not on my testnet.
I took the opportunity to clean up some of that logic generally. I need a
better testnet, but that will have to wait until we exit beta and hopefully
I can earn a little bit of money off this. A better testnet will require
a big beefy virtualization box or two to run hundreds to thousands of KVMs.

Also fixed a tiny cosmetic issue on Windows. Other than that no changes.
