- Refactoring: Move build-html to build directory

- Optimization: Remove old build/tools closure/yuicompressor code
- Testing: Produce mochawesome report
- Testing: Cypress with multiple reporters (was expecting we'd need, but doesn't hurt to add for now)
- Docs: Add testing badge
- Docs: Reprioritize `docs` in commit lists (prioritize user-facing)
- npm: Update `package-lock.json` (seems to have fixed so Cypress shows incremental results)
