[LDPatternCreator] Release 1.7.3 (new tangent primitives / bugfix)

[Nils Schmidt]

What was the problem exactly?

Bug details / how to reproduce:

•     Select "Add Vertex [A]"
  
•     Add a vertex. Watch out for the small coordination windows in the bottom right-hand corner
  
•     Select "Add Primitive [F7]... Create a Spline..."
  
•     Click to add the spline starting point
  
•     Click to set the first direction of the spline
  
•     Click to add the next point
  
•     Click to set the next direction
  
•     You CANNOT click to apply the segment count because the "Vertex-Data" is still there hiding the segment count window underneath.
