0.11.1: the arc42 examples cover all twelve sections

Numbered cards for the text sections (1.1-1.3, 2, 4, 11, 12) on the
overview, domain interfaces on the technical context, black-box
descriptions for every building block, blocks mapped to nodes in the
deployment view, crosscutting concepts on level 1, and a 1000-quality
folder with the quality tree. The example test checks each section's card.
