Classifieds - not SSL / HTTPS compatible

http://example.com/wp-content/plugins/classifieds/ui-front/buddypress/style-bp-classifieds.css is served HTTP even on HTTPS pages.

I didn't dig too deep, but /wp-content/plugins/classifieds/core/buddypress.php is the offender: Lines 290, 291, 292, and 293.
