Subject: Add JavaScript linting and tests

* Add sample malformed JavaScript files to lint on
* In our tests, copy the `node_modules` directory to make `jshint`
  available, then validate that we're correctly linting the staged JS
  file
* In our pre-commit hook, lint the staged JavaScript files. If either of
  our linting commands fail then exit 1 to abort the commit.
