Apply same link/content fixes to the Python variant

Mirrors the fixes made to the PHP feeds: correct link format
(/actualites|agenda/<slug>?u=<UID> instead of the wrong ?news=/?event=),
and full rich-text body + attachment links instead of the short teaser
only. Keeps both implementations in sync even though only the PHP one
is currently deployed.
