Automatic fixing of special boundary issue on meshes

Sometimes it can happen that a special boundary segment has no vertices
that are associated with the same special boundary. However, it is very
likely (otherwise you have bigger problems) that the adjacent segment
has at least one associated vertex. By simply rotating the triangles
(i.e. exchanging vertices) both segments can have at least one vertex
with the same special boundary id.
Test-triangle-size: only one failure output as standard

TTS used to spam if several triangles failed the test. Now there is a
define that limits it to ouput only the first failed triangle.
