Commented out some checks of the Relax_disp.test_hansen_cpmg_data_auto_analysis_numeric system test.

This is to allow this test to pass on 32-bit GNU/Linux systems. The numeric model optimisation is
incomplete but different between the 32-bit and 64-bit systems.

Loosened some of the relaxation dispersion system tests to allow them to pass on MS Windows.

Fixes to allow the Mf.test_mf_auto_analysis system test to pass on Mac OS X.

The simulated event.GetPosition() method in the Fake_right_click class the file
test_suite/gui_tests/model_free.py must return a wx.Point object and not a Python tuple. The
gui.components.base_list.Base_list.on_right_click() method has also been modified with a wx.Yield()
call to allos the test to pass.

Loosened the Relax_disp.test_sprangers_data_to_mq_ns_cpmg_2site system test to allow it to pass on Mac OS X.

Created a GUI element for the numeric_only flag of the auto-analysis for the dispersion GUI tab.

This defaults to false to allow all model types to be used.

Added a new button to the button bar in the relaxation dispersion GUI analysis tab.

This is a button used to launch the value.set user function to allow the user to pre-set certain
parameters so that they are not used in the grid search.

Completed the Relax_disp.test_hansen_cpmg_data_auto_analysis_numeric system test.

This now checks all the optimised parameter values and makes sure that no 'CR72' model was selected.

Implemented the numeric only option for the dispersion auto-analysis.

If the numeric_only flag is set to True, then no analytic models will be used in the final model
selection.

Fix for the hansen_data.py dispersion auto-analysis script used for a number of system tests.

The numeric_only flag was not being handled correctly.

Created list variables of all analytic and numeric dispersion models.

These are the MODEL_LIST_ANALYTIC and MODEL_LIST_NUMERIC lists in the module
specific_analyses.relax_disp.variables.
