gddo: Removed dependency on CDN for Bootstrap and jQuery

Downloaded the linked version from the CDN and stored it in the
assets/ directory. Removed the Bootstrap.js Bootstra.css and jQuery.js
definition from common.html. Changed all the occurence of these
to staticPath commands in the other templates.

Fixes #410
