While show_homepage_promo_video would previously toggle the control to play the welcome video on and off, the YouTube embed iframe would be included in index.html unconditionally. This created the ugly situation that YouTube would try to pull in a non-existent video, and that a DoubleClick tracking beacon would be introduced to the start page for no reason. Instead, make sure show_homepage_promo_video toggles the entire modal video section on and off, suppressing it altogether unless show_homepage_promo_video is set.
