Sankaku timestamps not working

[cpz3501]

When I download from sankaku with "filename": "{created_at}.{extension}", the filenames look like this {'json_class'_ 'Time', 's'_ 1531852126, 'n'_ 0}.jpg.

So the metadata entries changed a bit when switching to the beta.sankakucomplex.com interface. 537742c changes the created_at field to be a regular timestamp again.

On a side note:

• sankaku support in 1.16.0 is broken (Errors on login-restricted images after removal of Sankaku login support. #1182). Either use an older version or the dev snapshot.
• {created_at[s]} would have produced the timestamp as well
