코어파일 수정이나 db불러오는 거 없이,,

순전히 댓글의 들여쓰기 상태로 파악하도록 했습니다.

대댓글에는 원댓글 작성자명이 '@원댓글작성자명' 이렇게 표시됩니다.

게시판 본문글을 작성한 사람의 댓글은 배경색이 나오게 했습니다.

삭제된 댓글에 달린 대댓글이 없는 경우는 삭제 표시없이 그냥 없어집니다. 

(이 부분이 제 용도에는 맞는데, 다른 분은 어떨지 모르겠네요.)

테스트를 많이 거친게 아니라 오류가 있을수 있으니 원본은 꼭 백업해 두시고,

오류가 있으면 말씀해주시고, 감당이 안되는 오류가 있으면 이 글을 삭제 하겠습니다.

그리고 제 홈페이지 용도에 맞춘거라 디자인은 다소 이상할 거 같습니다.
