[ubuntu-art] Meerkat volume control design

[Dylan McCall]

While we're here, I was about to file a bug report about how it's a
little unpredictable that clicking the music metadata widget copies
its contents to the clipboard. Was there a particularly strong use
case for that? I keep wanting to click the music info to show the
music player, and I wonder if other users might be confused when it
doesn't. The current behaviour strikes me as inconsistent with other
indicators that have informational displays (like the current battery
level or the date).
