Results: a static step first shows its contours undeformed

The first look at a solved static step draws the von Mises contours on the
true geometry; the deformed shape comes when asked for (Deformed,
results.deformed, results.animate), at the automatic scale. Frequency steps
still open on mode 1 deformed and explicit steps at true scale, as the
owner's notes in #77 ask; a 0.24 mm deflection drawn as 10 mm no longer
reads as a failed part.

Fixes #77
