Updated the parameter value checks in the Relax_disp.test_hansen_cpmg_data_CR72 system test.

The low precision parameters are slightly different because of the new upper constraint on kex,
simply because optimisation is terminated early rather than optimisation giving different results.

Converted the Citations chapter of the relax user manual into a preface chapter.

Fix for the Grace string for the dw dispersion parameter.

The relax_disp.plot_disp_curves user function backend now sets clear legend boxes with smaller text.

The lib.software.grace.write_xy_header() can now set the legend fill pattern and font size.

Updated the model lists for the relax scripts for optimising Flemming Hansen's CPMG data.

The model lists now include the numeric models and the 'CR72 full' model.

Added an upper constraint of 2e6 rad/s for the kex dispersion parameter.

This is to prevent slow optimisation to values in the order of 1e20 for models which fail.

Fix for the model nesting method of the relaxation dispersion auto-analysis for deselected spins.

The Relax_disp.test_hansen_cpmg_data_ns_2site_expanded system test now passes.

The test has been set up to match Relax_disp.test_hansen_cpmg_data_CR72. This allows the efficiency
of each method to be compared by running the tests with the --time flag.

Fixes for the lib.dispersion.ns_2site_expanded module.

These problems were identified using the Relax_disp.test_hansen_cpmg_data_ns_2site_expanded system
test. They correspond to the issues with the original fitting_main_kex.py program identified by
Mathilde Lescanne in her post at http://thread.gmane.org/gmane.science.nmr.relax.devel/4144.
