One video player across OpenVibe

Recordings and clips on openvibe.video and videos on openvibe.media play in the network's own player instead of each browser's: a scrubber that shows what has loaded and the time under the pointer, volume it remembers, captions, speed, picture-in-picture and fullscreen, with YouTube's keys and a double tap to skip on phones. A live channel's player on openvibe.live has the same look, with one clock instead of two.
