I've got remarks from several users that have trouble understanding the concept
of having players bound to different music sources.

I would like to be able to separate the Music Source from the player control.
The way to do this for me would be to keep one connection for NowPlaying (to
the server the current player is connected to) and one for the database itself.

I would consider this only for those players and servers that are known to each
other - that is the players that will be shown on a serverstatus query.

This change would enable to get Squeezeplay/Controller menus for players that are known but currently not connected. Thus, menus to control players when taken over as proposed in https://bugs-archive.lyrion.org/show_bug.cgi?id=12156 would be enabled.

Ideally, this would only work for menus that are library related - content plus plugins that provide content - yet since there is no such logical separation in SC now I propose to allow this for all menus.
