// @history      0.2.0 'Download all', now has an option to compress all the individual .zip files into one zip with sub-folders. By default this will be on.
// @history      0.2.1 Added an option to compress the subfolders created from the single file download option.
// @history      0.2.2 Fixed a bug where it would trigger the download multiple times when the "single file" option was enabled and the "compress sub folders" option was not.
