[PATCH BlueZ v2 05/13] player: Add support for setting current Item object

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

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

This introduces media_player_set_playlist_item which is used when the
current item UID is known, with this the application can tell what
is the current item in the playlist.
