Reformat ApacheCon post, added Clocker talk and configured the quick new

Reformatted the ApacheCon post to show the title of the talks and also the avatar of the speakers. Also included a direct link to each talk, added the Clocker one, and configured the post to appear in the main page as a quick new.
