Play next/prev with volume long-press

[lukedirtwalker]

It would be great to have a option to use volume up/down keys for next/play-pause keys.

So it would work like this:

Normal short press of the volume key would just change the volume, but a long press for volume up would be equal to next track and long press for volume down would play/pause.
