BUG 5457035 : Anti-spoofing : DO NOT MERGE 

Squashed commit of the following:

commit 060b9daf5fe3c45573a13a149bf98f4fa1e6a46f
Author: Danielle Millett <dmillett@google.com>
Date:   Wed May 30 15:50:03 2012 -0400

    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.
