followup Ic8756e685: fix botched fix

Divs are not allowed inside p, consequently Parser::doBlockLevels() will not wrap paragraphs containing divs in p, leading to concatenated paragraphs in the final html code.

Solution: Revert from divs to spans. Instead use CSS to put each defintion on its own line

This has the nice side effect of improving accessibility of definitions for styling by introducing a dedicated class.

New CSS class means version bump.
