google fonts import with http

Hi!

We manage more webshops based on Commerce Kickstart. Now these sites are served with https.
We get error messages because the google fonts import using http requests.

"Mixed Content: The page at 'https://mywebshopname.hu' was loaded over HTTPS, but requested an insecure stylesheet 'http://fonts.googleapis.com/css?family=Open+Sans:400,300,600,700,400ital...'. This request has been blocked; the content must be served over HTTPS."

The importing code lines:
@import url(//fonts.googleapis.com/css?family=Open+Sans:400,700,300,600,800);
@import url(//fonts.googleapis.com/css?family=Gentium+Basic:400,700);

The code lines are placed into more css files, for example:
/profiles/commerce_kickstart/themes/omega_kickstart/css/global.css
/profiles/commerce_kickstart/themes/omega_kickstart/css/omega-kickstart-alpha-default.css
/profiles/commerce_kickstart/themes/omega_kickstart/css/omega-kickstart-alpha-default-normal.css
/profiles/commerce_kickstart/themes/commerce_kickstart_theme/css/commerce-kickstart-style.css
/profiles/commerce_kickstart/themes/commerce_kickstart_theme/css/commerce-kickstart-theme-alpha-default.css

We solve the problem temporarily by comment out these lines in css files, and import fonts in our theme with https.

I downloaded the latest version of Commerce Kickstart (7.x-2.48), and I see that these code lines are the same.

I want to ask change these requests to https.

Thanks.
