Fix for the right click pop up menu entry "Set the spin-lock field" in the dispersion GUI tab.

This is for the spectra list relax_disp.spin_lock_field user function call. The reference spectra
are now detected and the field value set to None. This fix has been propagated to the
relax_disp.cpmg_frq user function menu entry as well.

Fix for the display of the spin-lock nu1 values in the dispersion GUI tab.

This was reported by Troels at http://thread.gmane.org/gmane.science.nmr.relax.devel/4708.

The GUI spectrum element at gui.components.spectrum was at fault, the add_disp_point() method was buggy.

Better section spacing in the dispersion chapter of the manual.

Each model section is now on a new page.

Fix for the 'NS CPMG 2-site expanded' model equations in the manual.

Added all of the equations for the 'NS CPMG 2-site expanded' dispersion model to the relax manual.

These are essentially the source code modified to look good in LaTeX.

Fix for the amsmath LaTeX package in the user manual.

It needs to be after the hyperref package, as hyperref clobbers a number of amsmath features.

Modified settings script for R1rho test dataset.

A 20-25% speed increase for the 'NS CPMG 2-site expanded' dispersion model.

Many repetitive mathematical operations have been eliminated and the equations have been changed to
optimise the calculation speed.

Small corrections to r1rho settings script.

Shifted the 'NS CPMG 2-site expanded' model to the top of the CPMG numerical solutions in the manual.

This is because this is the default model which should be used in most cases.
