Subject: [PATCH] Disable dock audio settings if the dock doesn't have
 Bluetooth.

We should really have a separate string here to indicate
this case, but it's pretty late for that sort of thing, so I
left it at the generic "configure dock audio".

We might also want to dim this setting rather than popping
up a "Must dock phone first" dialog if the phone is not
docked.
