setInputView() was not called when the view was re-created through refresh_config(). Also, the refresh_config() function was not able to properly set the current layout. Now keep the default layout (_localeTextLayout) and the current non-text layout (if any, _currentSpecialLayout) separately to be able to refresh them later. setInputView() is called everytime the view is created instead of by onStartInputView() specifically. The setting activity now save the preferences to the protected storage in onStop() instead of listening for onSharedPreferenceChanged.
