Cannot search for Movies/TV's actors are in across libraries

[FordGuy61]

[implement] Show results from all available libraries under Actor view, not just the current library

Currently, if you view an actor in a Movie library, Plex will only show results from that library. Likewise for TV Show libraries. It would be nice if when viewing an actor, results from all available libraries (libraries visible to user) would be used, grouping by library. This way you could see all TV Shows AND Movies for a given actor in one location.
