- make the connection also working for frequency and buckling analysis by directly creating/updating the pipeline where the CalculiX results are loaded
- it was often criticized that our default solver CCX is not connected to the results pipeline system. One had to connect it manually, the create the different filter etc. but as soon as one changed a constraint and re-run the solver the whole work was gone and one had to recreate the pipeline.
This PR solves this by creating a pipeline and by reloading new results to it on a solver re-run.
The CCX results dialog feature is not touched, since the pipeline is hidden when the dialog is active.
