Switch default renderer for class diagrams to the next generation renderer

[knsv]

The new version of class diagrams have better looks & support for htmlLabels. This will be the default renderer from now on.

It will still be able to revert to the old version by changing defaultRenderer to 'dagre-d3' in your configuration under the class section.

The comment still says Default value: 'dagre-d3' btw.
