Use hook_field_attach_view_alter() Instead of hook_entity_view_alter()

After discussions with Kristof de Jaeger of DS fame, EVA views could be used as 'region to block' fields in display suite if we embedded the EVA view earlier in the node creation process. To pull this off, we'd need to move EVA's process of attaching the views to the node's build array from hook_entity_view_alter() to hook_field_attach_view_alter().

Shouldn't be too crazy. Anyone feel like giving it a whirl?
