Subject: [PATCH] align_from_ayoub: dedoublonne les domaines
 case/accent-insensitive
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Fusionne 'Flux Libre'/'flux libre', 'Péage'/'peage'/'PeagE' en gardant la
forme propre (avec accents et capitale). Update domain_environments.domain_id
vers le keeper et supprime les doublons.
