Release Procedure

When good, do npm publish. it'll run the prepublish script (build & test)
- complete publishing to npm. (we now have the tagged commit, too).
To complete the changelog: Do git log --oneline and then edit the resulting text to match the style in changelog.md. it's pretty manual. update that file. commit.
Push back up to origin. Do git push --tags to ensure the tag is there.
Open up https://github.com/GoogleChrome/chrome-launcher/releases and Draft a New Release. Use the same changelog.md markdown. Publish.
