Fix for the dauvergne_protocol - the maximum number of optimisation iterations is now an int.

The observers of pipe alterations should now all be thread safe.

Pipe changes in relax were causing segfaults in the GUI.

Backward compatibility fix for supporting old model-free auto-analysis GUI save states.

Missing numpy import.

The GUI dauvergne_protocol test now uses the same optimisation settings as the system test.

The diff_tensor_grid_inc dauvergne_protocol arg is now available in the auto-analysis GUI tab.

This is not exposed to the user though.

The dauvergne_protocol GUI test is now checking the same data as the equivalent system test.

The results from the dauvergne_protocol system test are now thoroughly checked.

The solution for the dauvergne_protocol system test is reached after 1 iter, so the test is shortened!

Fix for the dauvergne_protocol auto-analysis 'final' model.

The final stage of the dauvergne_protocol was broken. The data pipes here need to be created rather
than copied from the initial data pipe as results are being read into these pipes.
