Bump major version
Bump major version

This was a big one:
- generate coverage reports from both Node and GUI tests
- rename tests from unit & acceptance to Node & GUI to emphasize environment over test type
- remove globals in tests
- abstract Mocha behind test suite classes that can be used to define tests
- make it super simple to do visual regression tests by adding a new `vit` method
- remove debugging Node tests with Webpack in favor of Node inspector
- replace in-house git hooks with husky and lint-staged
- allow continuously running the GUI tests by not restarting Selenium between runs
- and probably more...
