Scroll HTML Exporter 3.9.19

Related information for the bugfix

Any exports generated with version 3.9.17 and 3.9.18 will have meant that the referenced files were not downloaded into the export temp directory - this was caused due to changes we made in a security fix in v3.9.17. Instead, downloads will have been directed to the Confluence process's current working directory. This means that any exports containing referenced attachments that were performed with either of these affected versions may require users to clean up downloaded referenced files from that directory. Please see the resolved issue for more information how to identify and clean up these files.
