MODified by Kai Gillmann, 19.01.2013, kaigillmann@googlemail.com:
VLC HAS already a youtube importer, but not for playlists. IMO this mentioned one is
better than this one, because it opens the video in the best possible video resolution.
So i decided to remove all parts of the code which is not responsible for list handling.
Now this lua script parses the list, as wanted, but for each video opened, the vlc default
Youtube script is used, so the videos will be displayed properly.

Patched by Aaron Hill (https://github.com/seraku24), 2018-05-16:
The original script was failing in VLC 3.x due to an overzealous probe function.
This patch makes the probe function more restrictive to avoid false positives.

It doesn't, I was trying to load the Yogscast TTT playlist and it stopped at 200 and wouldn't load more

i want to add a warning, i haven't tested the limits of the scripts but i can say that it only works if the playlist is public only.

VLC 3.0.9 - I can see the individual songs in the playlist once I open the YT playlist link, but it just skips over all of them.
