Add a mass delete scrobble option

I feel that this would be very useful when watching things like youtube videos and still having the pano scrobbler on, at least me, i dont deactivate the scrobbler never, and i watch youtube videos and have like 300 hundred scrobbles from youtube! or i fell asleep while listening to music and i have 100 scrobbles from the automatic reproduction of the app (i use Metrolist). that's all.. ty!
