Alles Doof...

Try to use only the ObjectContainer Connections and remove the static
list… did not work (an missing: The GShape needs also to know the
ObjectContainer to update the connections with different thicknesses)
Connections seems to work now after saving
...Murks, but now it seems works reeeeeally (even after restarting)
Merge branch 'refs/heads/notWorkingConnections'
