Comment 1 for bug 748805

Okay, I am attaching a branch that fixes this. It's my first time patching a patch (or using quilt), but hopefully I did it right :)
I decided to change our patch for gnome-settings-daemon, since the existing stuff was a little complex and it wouldn't look pretty inside indicator-sound. (I assume the settings daemon patch inherits that complexity from the original overlay, which had a fancy fading effect). With that said, the current gnome-settings-daemon patch is probably more consistent with upstream Gnome, so if there is a valid reason to do that here we should patch indicator-sound instead.

I discovered that the issue with indicator-sound's notification is unrelated: it generates a notification based on the previous state, instead of the new state. Filing a new bug report for it…
