Greenkeeper integration?

https://greenkeeper.io/ Once we have #16 we can think about greenskeeper integration. This will make sure our npm packages stay up to date by opening a PR with the module verison bumped. The CI will make sure tests pass and if they do, the PR will be marked as safe to merge.

👍 for Greenkeeper, otherwise we'll need to continuously manage package versions in all of the respective project repos. Note: connect with Jordan to see if there are any objections on her end.
