vid-thumbs: suppress ffmpeg stdout, fix vid toggle

Previous behavior on submission_listing was clicking a thumbnail would
toggle an inline video player. This was retained for clicking the
thumbnail off the `.video-play` element; however, directly clicking
the `.video-play` did not have the `toggleVideo` onclick event attached
and would navigate the browser to the video file directly.
