Subject: [PATCH] LP#1685840: Dojoless Google Books Preview as external script

Rather than including the JavaScript inline in each page, load the
JavaScript as a regular external JavaScript file so that browsers
can take advantage of caching, reduce network bandwidth, and reduce the
amount of TT2 processing required. Every little bit helps.
