Fixed Google Fonts API link to not throw browser warnings when use_ssl is turned on
Fixed Google Fonts API link to not throw browser warnings when use_ssl is turned on

Changed the link to the Google Fonts API stylesheet to use a protocol-less URI so that browsers do not throw HTTPS warnings when used with an SSL only Gitorious installation.
The browser determines what scheme is used for fetching the stylesheet depending on whether the page is called over HTTP or HTTPS.
[Protocol less URIs are valid and defined in RFC 3986 (4.2) http://www.ietf.org/rfc/rfc3986.txt]
