Some small edits to the intro chapter of the relax user manual.

Updated the screenshot of the analysis selection wizard to include the dispersion analysis.

This new figure has been updated in the intro chapter of the relax user manual as well.

Updated the intro chapter of the user manual for the now supported dispersion analysis.

This is no longer listed as a future to be implemented feature.

Reactivated Monte Carlo simulations for the 'R2eff' model for exponential data curves.

This is within the optimise() method of the dispersion auto-analysis.

Added an element to the dispersion GUI analysis for specifying the directory of previous results.

This is used for the pre_run_dir argument for the dispersion auto-analysis.

Implemented the new relax_disp.parameter_copy user function.

This is used to copy relaxation dispersion parameters from one data pipe to another, taking cluster
averaging into account. It is used by the dispersion auto-analysis to handle clustering.

The dispersion minimisation() method now skipped deselected spin clusters.

This is defined as all spins of the cluster being deselected.

Fix for the Monte Carlo simulations for the dispersion auto-analysis failing under certain conditions.

The wrong variable was being checked to see if more than two models were being optimised.

Added the new pre_run_dir argument to the relaxation dispersion auto-analysis.

This is to enable clustered optimisation. This specifies a directory containing a completed
analysis. The parameters from this previous run will be used as the starting point for optimisation
of the clustered analysis.

Small fix for the relax_disp.cluster documentation.
