This PR introduces a new secure media setting. When enabled, it prevent unathorized access to media uploads (files of type image, video and audio). When the `login_required` setting is enabled, then all media uploads will be protected from unauthorized (anonymous) access. When `login_required`is disabled, only media in private messages will be protected from unauthorized access. A few notes: - the `prevent_anons_from_downloading_files` setting no longer applies to audio and video uploads - the `secure_media` setting can only be enabled if S3 uploads are already enabled and configured - upload records have a new column, `secure`, which is a boolean `true/false` of the upload's secure status - when creating a public post with an upload that has already been uploaded and is marked as secure, the post creator will raise an error - when enabling or disabling the setting on a site with existing uploads, the rake task `uploads:ensure_correct_acl` should be used to update all uploads' secure status and their ACL on S3
