Release: Bring back Rollup, Add coverage, Add browser test

Follows-up 3708273. Now that I've had a while to take
inventory, I think we can bring this back to make distribution
and re-use a bit easier for things like browserstack-runner.

Highlights:

* Switch from 'chalk' to 'kleur'.
  Kleur is a a dependency-free alternative that is safe to run
  in a browser environment without needing to do anything extra
  to emulate Node etc.

  Downstream browserstack-runner was having to mock the Node
  'process' global previously because of this. There are ways
  around that, but it's naturally simplest to just not have any
  code that is just naturally agnostic of Node vs browser.

  Ref browserstack/browserstack-runner#179.

* Use Karma to run the unit tests in the browser.

* Use NYC to generate a code coverage report over the unit
  and integration tests.
