同じタイトルのページに対するサイドバーの挙動を修正

[Raclamusi]

発生している問題

開いているページと同じタイトルの別ページが（同じヘッダ内に）存在するとき、サイドバーでその別ページがアクティブになる問題があります。

例えば、 reference/chrono/duration/floor を開いたとき、サイドバーでは reference/chrono/time_point/floor がアクティブになります。
両方タイトルが std::chrono::floor であり、両方 <chrono> に含まれるため、この問題が発生します。

「機能テストマクロ」、「更新された定義済みマクロ」については #127 で修正しましたが、それ以外に92件もの同様の問題を持つページ組が存在することがわかりました。

修正のための変更

サイドバーの要素は IndexID をキーとする連想配列で管理されていました。
IndexID はページのタイトル（ 名前空間::(クラス::)?タイトル ）で決まるため、同じタイトルのページを区別することができませんでした。

そこで、 IndexID ではなく、ページごとに独立な Index をキーとするように変更することで問題を修正しました。

この修正により #127 の変更は不要になったため削除しました。
