#350285 by electronicmonkey: Added a possibility to have different templates for different newsletters.

#141635 by tcblack: Added support for choosing independently whether header, footer and style should be included in nodes with issues of a newsletter. The header, footer and style are always included in e-mails with issues of a newsletter.

#367599 by TBarregren: Fixed so that the title is not shown twice when viewing nodes with issues of a newsletter.

#329249 by spade: Added support for Simplenews' variable substitution tokens, e.g. %site, %uri, %uri_brief, %mymail, %date, %login_uri.

#344695 by enboig: Emogrify can't handle several CSS rules on one line. As a precusion, insert LF after each closing bracket.

Because mimemail_html_to_text() only matchs <style>...</style> when the opening and closing tags are on the same line, \n and \r in the style must be removed.

#345246 by guitarmiami: Fixed a bug in _simplenews_template_starts_with() that made phptemplate_mimemail_message() to call theme_mimemail_message().
