Styling and Interaction: Related Videos on the End of a Playback

[MaZderMind]

Since the last Geekend we have Releated-Videos Information on al Releases. They are currently visible underneath the Video.

There is also a second, less known view: When a Video has been watched completely until the end, a Overlay shows related videos (open https://media.ccc.de/v/dg63#video&t=2550, click play):

This view is not very usable and also very hard to find. The following changes would make this much better:

• [x] Fix visual appearance
• [ ] Show when Paused and remaining Playback-Time is <5 Minutes
• [ ] Hide when seeking / unpausing
• [ ] Autoplay the first result after 15 seconds (only when playback has ended)
