Show queue in Action list (when tapping on Cover art in Playback screen, for instance)

User can now select "Show queue" as an action when interacting (press,
long press, swipe up, swipe down) with the Cover in the Playback Screen.

I added this because I often check the current queue (usually one or several albums from the same artist) in order to switch to a specific song, and currently I have to click on the Menu button, then select "Show queue"...
