depositor link back to collection

[kjdon]

When using the depositor, once you have added a document, there is not an easy way to add another document. You have to click on the depositor link and start from scratch, choosing a collection.

And on the final page if you have depositonly, you don't even get the depositor link.

Make a link back to the first page of adding a document, for both sample workflows, so that you don't have to select the collection each time.
