* Newly added videos are now added to an aposVideos collection, for future reuse and possible gallery display (UI still to come).
* Video player height is determined by the aspect ratio of the video, not the aspect ratio of the thumbnail, as long as oembed provides the information. This works much better with YouTube even if the width differs from the video's official width. As long as the video is at least as wide as the videos' official width, black bars seem to be a thing of the past.
