Subject: Decrement renderer level after section recursion (#16)

The html renderer section level used for title numbering is incremented
when entering a new section so that subsections get correct heading
elements. Match the increment with a decrement after having rendered the
section contents, so that multiple consecutive sections would stay
consistent.

Add a test to verify this behaviour.---
