Freedesktop sound theme support in gnome-control-center trunk

[Bastien Nocera <hadess hadess net>]

Heya,

I won't dwell on the details. See
http://bugzilla.gnome.org/show_bug.cgi?id=542979 for them.

* For the i18n team:
I have a few sucky strings in there:
- "Play sounds when buttons are pressed" (MacOS X says: "Play user
interface sound effects")
- "Play system beep sound" (this enables the audible bell in X)

Ideas for better strings welcome.

* For the Doc team:
The interface changed, we removed a sucky sucky tab in the sound
capplet, and made the sound selection look much better

* For the release team and others:
The esound dependency in the control-center is gone, libsounds
copy/paste isn't used anymore, and libcanberra-gtk was added as a
dependency.

Enjoy, and please send bugs to bugzilla.

Cheers
