Added support for the 'NS R1rho 3-site' models to the relax_disp.select_model user function back end.

This is for the 'NS R1rho 3-site' and 'NS R1rho 3-site linear' CPMG dispersion models.

This follows the tutorial for adding relaxation dispersion models at:
http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax#The_relax_disp.select_model_user_function_back_end.

Changed the 'CPMG-type' to 'SQ CPMG-type' in the relax_disp.select_model user function frontend.

Changed the order of the experiment types in the relax_disp.select_model user function frontend.

The R1rho-type models have been shifted to the end so that the MMQ CPMG-type models are just after
the SQ CPMG-type models.

Added the 'NS R1rho 3-site' models to the relax_disp.select_model user function frontend.

This is for the 'NS R1rho 3-site' and 'NS R1rho 3-site linear' dispersion models.

This follows the tutorial for adding relaxation dispersion models at:

Added the 'NS R1rho 3-site' models to the dispersion variables.

This is for the 'NS R1rho 3-site' and 'NS R1rho 3-site linear' dispersion models.

This follows the tutorial for adding relaxation dispersion models at:

Created the Relax_disp.test_ns_r1rho_3site_linear system test.

This is for the 'NS R1rho 3-site' and 'NS R1rho 3-site linear' dispersion models.

This follows the tutorial for adding relaxation dispersion models at:
http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax#The_test_suite

Added cpmg_fit results for the Fyn SH3 R1rho test suite data using the 3-site numeric solution.

Created some synthetic data for the 'NS R1rho 3-site linear' dispersion model using cpmg_fit.

Updated the lib.dispersion.ns_r1rho_2site module docstring to explain the origin of the equations.

This includes the Korzhnev 2005 reference where the modifications come from.

Fix for the Palmer and Massi 2006 citation in the dispersion chapter of the manual.
