This PR fixes some tests, then adds travis to make sure they don't break again. To try travis I think you just need enable travis for this repo, then close and reopen this PR to get it picked up.
It also undoes a (possibly unintentional, cc @roman-kashitsyn) change from https://github.com/tylertreat/comcast/pull/34/files#diff-37cc0cdfa4b91e523551b72469d7abeaR129 where previously passing no IP addresses applies rules to all IPs, but afterwards it would apply to none (the iptables commands wouldn't be run at all). This manifests in the form of packet loss options not applying, though bandwidth limits still happen.
