Subject: [PATCH] BlogNav: Archive-Subtree immer rendern, off-Klasse steuert
 Sichtbarkeit
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

Jahre und Posts fehlten im HTML wenn man sich auf Categories/Tags-Seiten
oder außerhalb des Blog-Bereichs befand. Jahr-off-Logik korrigiert:
sichtbar nur auf Archive-Root (alle Jahre als Kinder) oder wenn aktiv.
