[[CHORE]] Verify integration with jshint.com

The jshint.com project website generates some content based on the state
of this repository. Changes in this repository could therefore interfere
with the website. This script verifies that when the website is
configured to use the current codebase, it builds successfully and
passes its own test suite.
