Subject: [PATCH] Bind 0-9, M, Menu keys when ListItemBase (slider) is focused.

These are the same shortcuts as alsamixer.
0 sets volume to 0%.
1 sets volume to 10%.
...
9 sets volume to 90%.
M toggles mute.

Menu button opens the contextmenu.
Enter will click the default device RadioButton.

A later patch will add Arrow Key navigation.
