…e-item
Make it possible to have linked SingleItem (sv: "Exemplar") inside Item hasComponent.
SingleItem is in collection none instead of hold so that we don't get any of the special handling for holdings
=> it is possible to have multiple SingleItem records per library
=> it is not involved in MARC export except as an embellished hasComponent of a regular holding record
Access control for holdings is extend to all subclasses of Item instead of just collection hold
i.e. only owning library + global registrant can write SingleItem

libris/definitions#494
Later on Item might be replaced by ItemHolding for the holding, with SingleItem and SomeItem for 1 vs many items.
See libris/definitions#483

(Om vi inte lyckas precisera att allakbv:hasComponenti bestånd är enskilda exemplar. Men det är både osannolikt och troligen inte önskvärt - det finns nog många "har två av denna på hylla X och resten i låda Y i källaren").
