Title: [MTLJSONAdapter] Add convenience method inserting arrays

I'm not sure if I feel comfortable with this (`__out NSArray`?), so I'm sharing for consideration. Perhaps we can improve it. But basically, this adds the ability to insert an array of models into a managed object context. This allows some to fail, but still progressing with the import.
