Title: If not using a pro account, then o_url not returned

See : https://github.com/openphoto/export-flickr/issues/6

So, I guess this should be better like this, not setting a null 'photo'.

Maybe there should be a warning for the user, and also maybe the option to still download a lower res image if user don't want to upgrade to be able to reclaim their originals.
