`go fmt` and other things

[jbenet]

I want to make sure all code pushed is run through go fmt. We probably want:

• a git pre commit hook
• a github integration that checks PRs (go fmt, go test)

This post (http://peter.bourgon.org/go-in-production/) also recommends:

on Save: go fmt (or goimports)
on Build: go vet, golint, and maybe go test
on Deploy: go test -tags=integration

cc @sqs thoughts?

Travis-CI is great for go test. (https://github.com/sourcegraph/srclib/blob/a672df5a0adaa762a66db579f7d13fa3aa6523e3/.travis.yml)

As for go fmt, in my experience 98% of Go contributors already enable it in their editor. But yeah, for accepting contributions, it's probably nice.

go vet/lint are not intended to be strictly adhered to in all cases, and there's no way of "ignoring" warnings, so those are probably best run manually or as optional steps.

thanks @sqs ! i've added go test with Travis-CI, and go fmt to the readme. that should be good for now.
