Remove embedded CDN hosting

[animedbz16]

It appears that this theme is leveraging embedded CDN hosting for some CSS assets:

• theme-faq/_layouts/website/layout.html

  Line 15 in e0f04d8

  href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css"

• theme-faq/_layouts/website/layout.html

  Line 19 in e0f04d8

  href="https://maxcdn.bootstrapcdn.com/font-awesome/4.6.0/css/font-awesome.min.css"

The problem with this is that if you are behind a proxy / firewall these requests will fail.

These dependencies should likely be installed via npm so that they can be served locally
