Demos break for users with HTTPS Everywhere extension

Thanks for dotJS! It's great and I have been using it in production for a client for the past year or so.

The script tag for jquery is http so the site breaks for users of the https everywhere extension for chrome and firefox.

I've submitted a pull request for this (https://github.com/olado/olado.github.com/pull/6) which I believe could be merged cleanly.
