github.com/apcera/termtables is no longer available, so go get -t -v ./... fails.

This is fixed in #89 by vendoring termtables.

Hello @troyspencer, I have made a PR with a fix little bit different from the one that you've proposed, can you check and it and tell me what you think?

Thank in advance

Looks good. I did the vendoring maybe a day after the dependency went offline as I didn't feel like supporting termtables myself.
