- adds new equation "Deformation" (this name since the stress solver got in FreeCAD the misleading name "elasticity")
- this way change icon of elastic solver to make the difference clear
- make the connection also working for frequency and buckling analysis by directly creating/updating the pipeline where the CalculiX results are loaded
