Add saving JS pages to static site build script

In previous commits we added a way to generate some of our static pages
after JavaScript had finished running. This commit adds this step into
the static site generation build script.

After `wget` has finished running this Rake task overwrites some of the
static files it generated with the (currently) few pages we want
enhanced with JS.
