Added a new section to the dispersion chapter of the manual for comparing different dispersion software.

This is an expansion of the table in the paper draft.

Added some lines to the end of the script UI section of the dispersion chapter about custom protocols.

Fix for the relaxation dispersion specific private _cluster_ids() method.

This was identified at http://thread.gmane.org/gmane.science.nmr.relax.devel/4716.

The cluster data structure was not being referenced correctly.

Added ZQ and DQ data to the TODO list in the dispersion chapter of the manual.

Correcting the R1rho settings script for the right calculation of the spin-lock offset, omega_rf, in ppm when offset values are provided in Hz.

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.
