Embed:

- updated videojs and dashjs
- combo selection algorithm now tries to find maximum simultracks
- when requesting stream info, add ?metaeverywhere=1 to the url to not count meta/subtitle tracks to simul_tracks and source priority sorting
- updated videojs, dashjs and hlsjs players
- improved html5 codec support testing
- urlappend: improved behaviour when url already contains search params
