Subject: Add excerpt to articles

* avandu.el (avandu-overview-excerpt): New face.

  (avandu--insert-feed-title): Replace `newline' with `insert-char' to
  prevent newlines from continuing indentation.

  (avandu--insert-article-title): Replace `newline' with
  `insert-char'.

  (avandu--insert-article-excerpt): New function.

  (avandu-list): Ask tt-rss to send along an excerpt of each article
  and print this excerpt after the article's title.
