Disallow adding an Item part to an Item that is not a BoundCollection

[rjyounes]

Domain class needs to be BoundCollection, not Item.

[rjyounes]

In the SHACL, there should be a BoundCollectionForm which sh:nodes the ItemForm but adds a property shape with sh:path bf:partOf. The general ItemForm should omit that property.

See LD4P/arm#102 for more discussion.

Workaround: manually change domain of faux property to BoundCollection.

Current workaround: hardcoded this change in ARMItem.n3:

Note that this change will be wiped out when this file is regenerated, so ideally would fix LD4P/arm#102.
