Smart playlists: add a AND kind of smart playlist
Right now we're making OR smart playlists, which means that
- "Series: Pokemon"
OR
- "Songtype: Opening"
will net you a shit ton of songs in a smart playlist. The OR criterias are fine for blacklists where you want to get different things to blacklist, but for smart playlists, they're already less useful.
We need to be able to change via a toggle in the criterias list if the smart playlist is inclusive or exclusive (or find another way to make it understable to the end user).
So the question is : how to tell the user the difference between a and/or playlist ?
