vendor dependencies with vndr (https://github.com/LK4D4/vndr)

[ijc]

Ran vndr init, sorted the resulting vendor.conf and committed the result.

In my first cut something regenerated AUTHORS for me, in my second go around that didn't happen so I forced it with rm AUTHORS && make AUTHORS.

Looks like the travis config needs some love to not try and vet vendored deps

[ijc]

Actually, I think all of vet, build and test in the Makefile could do with that. I'll look at it.

Seems like the go version could be bumped too it's currently 1.7, 1.8 and tip, I proposed to add 1.9 and drop 1.7.
