http://bugs.debian.org/660483
http://bugs.debian.org/658717
* New upstream release.
  - New more compact header layout, including album art.
    Closes: #660483, #658717
* debian/watch: Also track odd version numbers since rhythmbox does not seem
  to follow the typical GNOME versioning scheme.
* Remove patches which have been applied upstream.
* Update librhythmbox-core5 → librhythmbox-core6 for the soname bump.
* Add explicit Build-Depends on libxml2-dev (>= 2.7.8).
* Drop artdisplay plugin. It has been removed upstream as it is no longer
  needed now that the playing track display includes album art.
* Drop Build-Depends on python-gst0.10-dev and replace Depends on
  python-gst0.10 with gir1.2-gstreamer-0.10 (required by the replaygain
  plugin).
* Drop Recommends on nautilus-sendto. The sendto plugin is for sending
  selected tracks by email or instant message from within rhythmbox. It is
  not a nautilus-sendto plugin.
