Reimplemented as a Foreground Service just so it can get on top of the Car Dock App. Added debounce mechanism to not disconnect immediately after getting a undock event. Each dock now has its own "Remember setting". Remember Settings is on by default Change-Id: I80790bdb7c831e2a642365b92433012191aa70c1
