*Add WidgetGtk::ClearNativeFocus so that subclass can implement cutomized behavior when clearning native focus.

 This is necessary in ScreenLocker as the focus has to be set to the widget that is grabbing all input focus.

* PasswordField that will set focus it itself when mouse is clicked. This is necessary again when the input is grabbed by
 other widget because the gtk textfield will never receive mouse event.
* fix minor bug : locating the grab widget in wrong place.
