 * 注) autoplay 時 pauseOnHover を false にし, arrows をクリックすると２つ進んだ
 *     りする.autoplay 時は pauseOnHover に.
 *
 * ※ MobilySlider のアップデート時には,以下の変更点を再度反映.
 *
 * - 2011/04/07 T.Nakamura
 * ・arrows が有効になっていてもスライドさせる領域が１つしかなければ,"前へ&次へ"
 *   の表示をさせないように修正.
 *   create:function() 内, if(sets.arrowsHide){ → if((sets.arrowsHide)||(l==0)){
 *   に,その少し先の arrows.show() → if(l>0){arrows.show()} に改変.
 *
 * -2011/06/20 T.Nakamura
 * ・autoplay でアクティブな bullet の更新が主画面更新後では遅く感じられたので,
 *   autoplay:function() 内の slider.bullets.update() の Timeout の設定値を変更.
 *   sets.animationSpeed+300 → 400 .
 * ・slider.bullets.update の際,また,bullet をクリックされた際に何か別の処理をす
 *   るスクリプト preUpdate(cnum) を用意した.引数は,アクティブな bullet の番号.
 *   作者がアニメーション前の処理用に用意してくれた animationStart:function() は,
 *   クリック時処理があるため使えなかった.外部で preUpdate(cnum) を上書いて使用.
