Logo en remplacement de la vitrine : centre et reduit (contain)

Quand un adherent n'a pas de photo de couverture mais un logo, le logo
n'est plus etire en plein cadre : il est centre et contenu (~80%) sur
fond blanc. Composant partage VitrineImage applique a l'annuaire, au
carrousel d'accueil et a la fiche adherent.
