Rockbox

I think it's an useful and easy to implemente feature. It consist in two task executed from dynamic or static playlist contextual menu.

First one is to remove duplicated entries in the playlist. Because sometimes you add songs to static playlist in catalog as you listen randomly from a bigger playlist, it isn't uncommon to add twice or more times the same song.

The other is because you sometimes remove music from the jukebox and keep playlists updated is hard work. Rockbox detects when a file in playlist is missing and skip it, but some cleaning tool could be great.

Thanks!
