Attachments: Mixed content download

[hoizfux]

Google Chrome in Version 87 is blocking download of most file types when it happens over mixed content (https --> http).
From Version 88 it will block every file type downloading over mixed content.

It would be great, if there is an option to enable/disable HTTPS for view-link and download-link in GET message REST-API.

Good idea. I'll need to figure out how to explain it in the config concisely without making people think they are actually enabling an HTTPS server.
