Add NightwatchJS Tests

If you could use Nightwatch against a rendered node with a known issue, as a logged-in editor, you could then load the dashboard as an admin to see if the logged issue is present.

The presence of that one entry would check a TON of stuff in one hit:

• Auto-provisioning of default permissions to view the module
• DB tables set up
• JS checker library loaded on page
• JSON reporting route operating correctly
• Dashboard working and showing issues
