Add Dock USB Audio Support for Samsung Car / Desk Docks 2 of 2

This adds a new Tab in the GalaxyS2Settings.apk called Dock

There is a new section in this for Dock Audio.
A new Checkbox sets the users preference to route the Dock Audio

On Startup or when the checkbox is changed, an intent is fired

This intent is recieved by the services/java/com/android/server/WiredAccessoryObserver.java
