Plyr UI Upgrade

Last week I pushed a UI upgrade as part of Plyr v1.6. The problem with the controls being underneath the video is that it breaks the aspect ratio of the video making it hard to calculate height using the classic 56.25% method (for 16:9). This way the controls are overlaid and are shown on mouse movement or focus in (for keyboard users) but you can set them to be persistent of course.
