Set up dev services

[hawkw]

I don't know if we'll actually want to run CI builds of the front-end unless we end up writing unit tests for front-end components, and I don't know all that much about unit testing for JS. However, Codacy has static analysis for JS and CSS, so we might want to look into that.

If we do end up using this repo for front-end dev, we'd probably want to hook it into Slack as well. Might want to have separate #frontend and #backend channels so we don't get swamped with status messages from both repos, especially if we end up onboarding additional devs (I've mentioned it to at least one other person).

I think @redbassett set up Codacy a bit ago.

I'm in no rush to CI it, but if we are adding a build tool, we may want to as part of that.
