Lockscreen: enable longpress on expand challenge handle (2/2)

 If enabled it will be possible to longpress the little lock icon.

 If it is an unsecure screen lock then the longpress will unlock the device.
 If it is secure then the widget will fade into the background and you need
 to enter the pattern, pin, password or whatever.

 PS2: better description - thx Nitroz
