qdoc: Add id attribute for all HTML headings

The HTML generator only added an id tag for h2 (\section1) headings
for unknown reasons. \section2 and up relied on the obsolete method
of using <a name="..."> anchors for the section headings.

Remove this restriction to make the output more consistent.
