* BOOT LOADER
* サーバーからレスポンスされるHTMLに埋め込まれるスクリプトで以下の役割を持ちます
* - 翻訳ファイルをフェッチする
* - バージョンに基づいて適切なメインスクリプトを読み込む
* - 事前に挿入されたCLIENT_ENTRYを読んで適切なメインスクリプトを読み込む
* - キャッシュされたコンパイル済みテーマを適用する
* - クライアントの設定値に基づいて対応するHTMLクラス等を設定する
* - もしメインスクリプトの読み込みなどでエラーが発生した場合はrenderErrorでエラーを描画する
* テーマをこの段階で設定するのはメインスクリプトが読み込まれる間もテーマを適用したいためです
* : webpackは介さないためこのファイルではrequireやimportは使えません
