Enable artist playlists in YoutubePlaylistIE 

Artist playlist pages have different format compared to user playlists,
thus more format checking is needed to construct the correct URL.

From the artist playlist this method downloads all listed below the
"Videos by [Artist Name]" header, plus usually there's one more
video on the side, titled "Youtube Mix for [Artist Name]", which
has a link format that currently cannot be distinguished from the other
videos in the list.
