Support item parameter for CSV import

[kenwenzel]

If a CSV file is uploaded then currently the headers need to specify the item and the property in the format
<item IRI>@<property IRI>

If the item is the same for all rows then it could be specified by using the HTTP parameter item.

yes this can be a next step (specifying context and item as HTTP parameter). For testing purpose in some actaul projects, i think it is suffiecient for now to specify the item and the property in the format
<item IRI>@<property IRI> , or do you see it something else?
