downloaded CDN dependencies to simplify local and offline development

I had some errors when trying load index.html from my local computer.
I'm running Gentoo Linux and I tried on both Chromium 32 & Firefox 24 and got the same issue.
See attached screenshot below:

This is probably a downside of the RFC1808.
To fix the issue I've added all the dependencies to git, this would also ease offline development.
