[Update] Config Window: Translation Tab: add "Use Translation Feature" and "Select Internal Translation Model"

翻訳機能そのものを使うかどうかの設定と、内部翻訳モデルの選択UI追加

・Use Translation Feature からは True or Falseを渡し、config.USE_TRANSLATION_FEATUREへ保存します。
・Select Internal Translation Model からは 文字列 "Small" か "Large" を渡し、config.WEIGHT_TYPEへ保存します。

※機能側実装に合わせて、初回起動時config.WEIGHT_TYPEには"Small"ではなく"m2m100_418m"が入ります。
※それに合わせ、起動時はSmall固定にしています。文字列"Small"対応後、一つ下のコメントアウト部分と入れ替えてください。
