volume control changes

[Matthias Clasen <mclasen redhat com>]

Hey, just thought I should mention that we are currently landing some of
the volume control improvements in rawhide that we are working on for
F11. See http://fedoraproject.org/wiki/Features/VolumeControl for more
details. After things have settled, you should notice that the mixer
applet is gone and instead a volume control icon shows up automatically
in the notification area. 


Feedback appreciated, Matthias
