 * QueueAnimation.jsの導入が必須です。
 * このプラグインより上に配置して下さい。
 *
 * <使い方>
 * イベントコマンドの「文章の表示」中に、
 * 制御文字 \E[演出ID] で演出のON/OFF、種類を切り替えます。
 * また、ページが変わると演出はOFFになります。
 * 
 * ◆演出ID
 * 0 : 演出なし
 * 1 : 強調
 * 2 : ゆれる
 * 3 : ゆれる(強)
 * 4 : フェードイン
 * 5 : フェードアウト
 * 6 : フェードインアウト
 * 7 : 歪み
 *
 * ◆使用例
 * この文章は、\E[1]ここから強調エフェクトで、\E[0]ここから元に戻ります。
