Add Q number to the "Items portrayed in this file depicts" entry of a photo it uploads

When WSM uploads an image, it’d nice if it added a back-link to the item it was uploaded to represent.

In other words, add Q number to the "Items portrayed in this file depicts" entry of a photo it just uploaded.

Perhaps also copy the descriptions in each language in the entry to the captions on the image and the values of the “instance of’s “ as categories on the image
