Removed protocol on third-party scripts

If I load the web site in https, so https://trevanhetzel.github.io/barekit/ the third-party font library is blocked due to being insecure.

>Mixed Content: The page at 'trevanhetzel.github.io/' was loaded over HTTPS, but requested an insecure stylesheet 'fonts.googleapis.com/css?family=Satisfy|Roboto+Condensed:400,300'. This request has been blocked; the content must be served over HTTPS.

This pull request makes those request protocoless so that it'll load fine in http and https.
