[PATCH BlueZ 03/14] client/bluetooth-player: Add proxy handling for org.bluez.MediaPlayer1

[Luiz Augusto von Dentz <luiz.dentz@gmail.com>]

From: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>

This adds proxy handling for org.bluez.MediaPlayer1 so changes to the
proxy are printed in the output.
