[gnome-music/wip/mschraal/core: 61/164] player: Rename PlayerPlaylist index to position



commit b0c20f00b0eb313d2b79dc00f19fdc73f8f8c985
Author: Marinus Schraal <mschraal gnome org>
Date:   Wed Jun 5 12:51:47 2019 +0200

    player: Rename PlayerPlaylist index to position
    
    Position fits better.
    
    This currently clashes a bit with Player get/set_position, need to consider
    this at some later point.
