Gmap SSL compatibility

When including a Gmap it always loads a non-SSL version (http).
So when my site is available via https, modern browsers do no load insecure content. Therefore all you see is some blank space.

Please implement https-support for the Gmap Shortcode. When loaded via https, include the SSL-version of gmaps and when loaded via http, include http gmaps.

Thanks in advance!
