Added support for image attachments by converting Markdown image tags into CIDs and adding the corresponding attachments. At the moment all image tags are parsed as attachments -- external resources, such as http://, are not respected. Default newsletter now depends on markdown-it-anchor and markdown-it-deflist -- this should probably not be the default.
