Feature : Volume adjust sound preference 1/2

Adjusting the volume makes a nice "boing" sound
Personally I find this annoying
This patch makes this a preference in
Settings | Sound
    Volume adjust sound
        Play sound when adjusting volume with hard keys

The Checkbox is defaulted to ON (1 in defaults.xml)

Look for 2/2 for the Settings, Sound Panel Change
