Subject: [PATCH] ox-rss: Prevent dropping lower level headlines

* contrib/lisp/ox-rss.el (org-rss-headline): Transcode lower level
  headlines (headlines with level > 1) with org-html-headline. Do not
  drop them.

Previously, lower level headlines were dropped and did not appear in the
exported RSS output.
