액션바 + 탭에 PreferenceFragment 추가

안드로이드 SDK 5.0.1 (롤리팝) 프로젝트 생성 시 네비게이션 스타일을 액션바+탭 선택하면 자동 코드가 만들어지고, 탭에 PreferenceFragment 넣기
Tab PrefFrgmnt.zip(AndroidStudio)

Fragment 추가 시 문제없으나 PreferenceFragment 추가하면 오류가 나므로 import android.support.v4.app.* 을 
import android.support.v13.app.* 로 대체 함, 58번줄 getSupportFragmentManager()을 getFragmentManager() 로 바꿈.
v4는 2.2(Froyo_ 지원, v13 은 API 13 부터 지원
프로젝트 선택하고 File/Project Structure.../Dependencies 탭/+ /Library dependency 눌러 v13 추가
