(ffa166343) Workshop fixes: - Refresh content package file in the staging folder when adding/removing files, not just when publishing. - Allow multiselecting files in the "add files" dialog. - Fixed autoupdating workshop files not working because Workshop.GetItem doesn't query the time the item was modified. - Some extra exception handling.
