Preserve Historical Queue Items

[willmahoney370]

An option to  preserve songs historically in the queue, rather than discarding them after play. Meaning you can backwards skip through past queue songs, and play (or skip) forward through the same songs again. Prevents an accidental skip from requiring a re-queue and re-order to the front, and allows replaying a queued song post-play (without double-queuing prior). Makes queues feel less “touchy” and easy to lose.
