Some more SetValue calls are having the data pass through str_to_gui() first.

All data passed into wxPython SetValue calls now go through gui.misc.*_to_gui() functions.

This ensures that the correct data type is sent into the GUI elements.

Deleted the now unused gui.execution.calc_rx module.

Fix for the stereochemistry auto-analysis - the pipe_name arg does not exist in this auto-analysis.

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.
