한글 두벌식 옛글 자판 초기 구현

자판의 배열을 아래한글의 두벌식 옛글자판과 동일하게 맞추었다.
초성과 종성을 뒤바꾸는 코드에서 UNICODE 5.2 버전의 옛한글을 지원하도록
하였다. 기존 두벌식에서 사용하던 hangul_jongseong_dicompose() 함수로는
옛한글 처리를 할 수가 없으므로 새로이 hangul_jongseong_get_diff() 함수를 
구현하고, 이 함수를 이용하여 구현을 변경하였다.
그러나 아직 버그가 있으므로 차츰 수정해 나가도록 한다.
또한 옛한글을 지원하는 과정에서 현대 한글 두벌식 자판에도 영향을 미쳤으므로
이 역시 차츰 수정해 나가도록 한다.
