Ensure file upload duplication works in IE7

There were two issues here. The first was that the duplication didn't
work as expected due to trying to `unwrap` fields with errors. Changing
the selector on the unwrap now works better.

The second issue was that IE doesn't always fire change events for file
inputs which are dynamically added to the page. This was stopping you
from ever getting more than one file input. I changed the event to a
click which, while causes the new attachment box to generate sooner. Is
more reliable.

Reloading the document series data for decc

This is becuase data was imported with invalid document serieve
missing, instead of haluting the import. So we are reload this data and
add any EditionDocumentSeries which are missing.

NB: I manually had to check and clean up the slugs as the excel method
is not the same as our regex.

Change created at column to updated by in admin

I have updated the version model to return nil when it doesn't have a

always have a value in reality.

Script to output non document admin -> public urls

I've renamed the existing dump all documents script and extended it to
include many different types of admin links that we need to convert to
public links.

This was given to Robin manually; the right solution will be to build
this into the redirector workflow. At the moment, the
document_mappings.csv is used for two different things: mapping old ->
new urls and mapping admin -> public urls. The data we need in each
overlap but are not the same.

This file provides a union of those as a workaround, but this process
needs revisting soon.
