// @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.
// @history 0.3.0 ALso added the basis for download trying to download something with pagination. However, this is disabled until I solve the issue of running out of memory while doing it.
// @history 0.3.1 Fixed an issue caused by classnames being changed on the site.
// @history 0.3.2 Fixed the URL match since it was changed.
// @history 0.4.0 Updated the script to work with the new use of Ractive.js on the 8muses website.
// @history 0.4.1 Fixed some css to better match the site.
// @history 0.5.0 Fixed Image links and more
