This moves a few helpers from `lib/` to `services/`: build-status.js build-status.spec.js color-formatters.js color-formatters.spec.js contributor-count.js licenses.js licenses.spec.js php-version.js php-version.spec.js text-formatters.js text-formatters.spec.js version.js version.spec.js And one from `lib/` to `core/`: unhandled-rejection.spec.js The diff is long, but the changes are straightforward.
