Stamps annotations not displayed because of missing AnnotationTemplateCatalog

The BlobAnnotationAccessor class should be reviewed because it doesn't allow us to load stamps on the Arender UI. BlobAnnotationAccessor creates an AnnotationCreationPolicy without setting any AnnotationTemplateCatalog. So, in the BlobAnnotationAccessor builder, we should add the following lines :

creationPolicy = new AnnotationCreationPolicy();
catalog = (AnnotationTemplateCatalog) DependencyInjection.getBean("annotationTemplateCatalog");
creationPolicy.setAnnotationTemplateCatalog(catalog);

Note: The annotationTemplateCatalog bean is defined in annotationtemplate-catalog.xml (WEB-INF/classes).
