Per WP review #20513, delete sniffer for Yoast SEO

Apparently wp.org cannot have themes that sniff for plugins. I feel this reduces the theme's effectiveness since many newbies don't know to use Yoast's plugin. However, for now am doing what it takes to make the theme live. Hope to get back to this at some point.
