Feature request: Per-user folder permissions

[jgdye]

It would be nice if we could set per-user folder permissions, so that each user's all file view and folder list would only contain items in folders they had permission to view, similar to Airsonic. A couple of use cases I can think of are families with multiple users with very different musical tastes or parents wanting to have access to explicit content without providing access to their children, while letting the children have access to the rest of the music (and possibly even having the reverse case, where the children have access to "kid's music" that the adults don't want making it into a random playlist for themselves).
