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.

Added test data where both the spin-lock time, the spin lock offset and the spin lock field is varied.

The data is published in:
A Folded Excited State of Ligand-Free Nuclear Coactivator Binding Domain (NCBD) Underlies Plasticity in Ligand Recognition.
Kjaergaard, M., Andersen, L., Nielsen, L.D. & Teilum, K. (2013).
Biochemistry 52, 1686–1693

with experimental conditions that
"off-resonance R1rho relaxation dispersion experiments on 15N were recorded at 18.8 T and 31 C."
"using the pulse sequence of Mulder et al. with spin-lock field strengths from 431 to 1649 Hz and offsets ranging from 0 to 10000 Hz."
