Submitted results can be downloaded by submitter

@mauvilsa :

"I need to download one submission that I did (the PRHLT-char-lm from the ICFHR2016 HTR competition). In scriptnet is there any way to download a submission? I have been looking for such an option but haven't found it. Is there such a possibility?

If not implemented, it would make sense that every user can download its own submissions and in the admin have the possibility to download the any of the submissions. "
