description:
- PeerTube: it's now full description (it cut at 250 characters before), and it displays ok (newlines are ok, but markdown isn't)
- MediaCCC: descriptions are now displayed well (newlines added)
- YouTube: timestamps in descriptions are clickable and work
more PeerTube fixes:
thumbnail is now high quality
age limit is now handled
upload date in «recently added» feed is good now (it was one hour delayed)
all fixes come from https://github.com/TeamNewPipe/NewPipeExtractor/pull/239, so it need to be merged before this PR
