This changes the organization of lock screen security settings to make choosing an alternate unlock method more discoverable. Instead of having to disable the old lock method to use a new one, the user now just has one set/change option in lock settings, with a list of method-specific setting below it. In addition, we ask the user to confirm their old credentials before prompting them to choose a new one, which eliminates one source of confusion. Also, ChooseLockGeneric now shows a UI if quality isn't specified. Any unlock method less secure than minimum specified by DevicePolicyManager (if active) is greyed out.
