TODO
   ・Icons
   ・動的な command の追加削除 (nice rabbit!)
   ・ツールチップみたいな物で、マウスオー馬したときに動画情報を得られるようにしておく。
   ・外から呼ぶべきでない関数(プライベート)をわかりやすくしたい
   ・argCount の指定が適当なのを修正 (動的な userCommand と平行でうまくできそう？)
   ・実際のプレイヤーが表示されるまで待機できようにしたい(未表示に時にフルスクリーン化すると…)
   ・isValid とは別にプレイヤーの準備が出来ているか？などをチェックできる関数があるほうがいいかも
      -> isValid ってなまえはどうなの？
      -> isReady とか
   ・パネルなどの要素にクラス名をつける
   ・上書き保存
   ・Fx の pref と liberator.globalVariables の両方で設定をできるようにする (Setting)
   ・ext_setInputMessage(String, String)

MEMO
   ・prototype での定義順: 単純な値 initialize finalize (get|set)ter メソッド
   ・関数やプロパティは基本的にアルファベット順にならべる。
