Accommodate production environment (#46)

* Move tech-stack ID from a body class to a div.

This makes the page more consistent with the version on redhat.com, which can't modify its own body tag.

* Remove image that had been added in error.

* Move image URLs out of JavaScript; remove commented-out code and console.log.

* Point to updating documentation
