Enhancement request: Smartplaylist support

[brett]

It would be nice if alternatives could be specified using a smartplaylist instead of tagging individual artists, albums, or songs.

Think queries with flexible tags are fine.

It would be nice if I could select some playlists, and import everything in these playlists

With the playlists plugin you can use the query onplaylist, after setting up the folder for playlists.

I think we could do something like that, putting a "Playlists folder" in the config, and then doing 'onplaylist:"%s"' for each playlist in the folder.

The playlists folder could be inside the "directory" config and, if two playlist with the same filename have different contents, we copy the 'local' playlist to the alternative dir. In case of links, we only check the 'onplaylist'.
