Some chutney tests fail when localhost is the only available IP
When I turn off the Wifi / Internet connection on my Mac (OS X 10.10.2), the chutney Exit tests fail with 'no exit to that port', but the hidden service tests are fine.
This is probably a misconfiguration around the localhost exit ports (all ports should be allowed, or, at the very least, the ports chutney uses should be allowed).
I'll see if I can find time to track this down and fix it, but it's low priority, as most people run chutney on a computer with an IP address apart from localhost.
