#20110131. MoonYoungShin. 멈춤버튼실행여부판단.
#20101005. (주의!)SF,CR만offsetHeight다른값해결: js이전에css가와야함.
#20100522. MoonYoungShin. Revision
mtickerEl[i].style.display="none"(mtickerEl[i].cont.offsetHeight=0)일 경우 카운터 count=0 상태로 멈춤
마우스오버시멈춤, 호출수로스피드,지연시간보정, 컨텐츠1번렌더링, 줄별너비무관(더미li불필요)
#20100105. LeeYoungSeok. 복수라인노출시(총개수가 노출수의 배수가 아닐때), 버튼prev 및 루프리셋문제 해결&delay인자='none'으로 루프해지
'none' 이 들어간 조건문식이 삽입됨
movemTicker()의 마지막 if문 부등호가 다름(==에서<=로)
prevmTicker()에 magicNum 이라는 변수생성 하여 경우의 수에 대응
