Fixes for broken icon names in the model-free GUI auto-analysis tab.

These bugs are not present in released versions of relax.

Improvements to the data-type labelling in the dispersion chapter of the user manual.

Updated the relax results files for the CPMG data from Korzhnev et al., 2005.

Fix for the interpolation for the numeric CPMG-type models in relax_disp.plot_disp_curves.

Improved the text for the relax_disp.plot_disp_curves user function.

Interpolated curves are now produced for the numeric CPMG-type models.

This if for the relax_disp.plot_disp_curves user function. The resolution of these are limited to
the frequency of a single CPMG block in the relaxation time period. Therefore the plots are
produced slightly differently.

To enable this functionality, the new count_exp() and return_relax_times() functions have been added
to the specific_analyses.relax_disp.disp_data module.

The relax_disp.plot_disp_curves user function now places the X-axis at zero.

This is for better visualisation of the residuals.

The lib.software.grace module now supports setting the X and Y axes at zero.

The relax_disp.plot_disp_curves user function now produces interpolated dispersion curves.

For this the new 'num_points' and 'extend' arguments have been added to the user function to give
the user better control of this plotting. The interpolated curve is disabled from the numeric CPMG
models as these do not support interpolation, and the 'R2eff' model as interpolation is not needed.

To support this, the specific_analyses.relax_disp.optimisation.back_calc_r2eff() function has been
extended to support the CPMG frequencies or spin-lock field strengths been supplied instead of
retrieved. This allows a set of custom dispersion points to be used in the back calculation.

The dispersion target function setup was modified to prevent the recalculation of tau_CPMG values
when asked, as interpolation is not compatible with this.
