BUG 5457035 : Anti-spoofing : DO NOT MERGE

Squashed commit of the following:

    Added head turn option for Face Unlock.

    In security settings there is an option for head turn and it shows the current
    status (on/off).  Clicking on this goes to another screen that describes the
    feature and allows the user to it on/off.
    Since the head turn option goes to a different screen instead of using a check box,
    this change also rips out the rest of the code for the old liveliness checkbox.
