Issue #512: Error in detail mode because auf wrong curve direction

New issue 512: Error in detail mode because auf wrong curve direction https://bitbucket.org/valentinateam/valentina/issues/512/error-in-detail-mode-because-auf-wrong

Holger Pandel:

When you try to add a seam allowance to a part which consists of lines and curves, and some of the curves don’t run in clockwise direction, the seam allowance is displayed wrong.

See attached pictures: The curve SplPath_TukL_TukR doesn’t follow the overall path for the seam allowance in clockwise direction, as the curve SplPath_KlL_KlR does. As you can see in detail mode, the top curve is drawn correctly and the bottom curve is missing completely.
