Sync to tag or revision for OneCRLTools

[mwobensmith]

Ideally, known good releases of OneCRLTools could be labeled with tags to make it easy to sync to. However, it is also possible to sync to git revision, so we could consider that as well.

pip install git+git://github.com/username/project.git@2927346f4c513a217ac8ad076e494dd1adbf70e1

While pip has very good support for fixing package versions to git branches, tags and even commits, Go packages like OneCRLTools instead need to go through go get / install which seems to have none of that. In #58 I elaborated a bit on a possible workaround that makes use of tags. We could probably make this work as soon as @mozmark pushes release tags to his repo.

I had a chat about this with @mozmark during our work week. He seemed keen on publishing release tags, so we can then sync to those. @mozmark, do you already know when you can get to this?

This has been prepared in #107. What's left to do is to pin to the new release tag that @MGoodwin just introduced to his repo.
