[gnome-music/gbsneto/untangle-player-window-mpris: 7/10] player: Receive a GtkApplication

[Georges Basile Stavracas Neto <gbsneto src gnome org>]

commit 72538c3afa15ce39457326bc20f7fd68bde89fc8

    player: Receive a GtkApplication
    
    Instead of receiving a window, receive the application
    itself. This way, all ties between Player and Window
    are cut, and we can move to where it actually belongs
    to: application.py.
