lrwshow-X 2.1 does not work with Rhythmbox3

[qingfeng.xia]

I have partially fixed this error (it works, but i do not know how to get Metadata property),
 i will upload my source code: not patch

Reason:
Ubuntu 12.04 Rhythmbox 2.97 lrwshow-X 2.1

The 'org.gnome.Rhythmbox3.player' interface was removed as the MPRIS interface provides all the same features,
is better designed, and works with other software too.

qdbusviewer will show all interface

 dbus-send --session --type=method_call --print-reply --dest=org.freedesktop.DBus /org/freedesktop/DBus org.freedesktop.DBus.ListNames

MPRIS D-Bus Interface Specification

Hi qingfeng, I don't have rhythmbox, and hard to install, you know, gentoo. If you think you rhythmbox supporting would be better, I will commit and release in the future.

Any help for the project is appreciated. Thank you.
