Decreased the number of models presented to the user in the dispersion sample scripts.

The dispersion sample scripts now have the NUMERIC_ONLY boolean variable defined.

Fix for the optimised parameter printout - the parameters are now scaled.

This problem was only recently introduced.

Converted the 'IT99' dispersion model parameters to pA and dw.

This is thanks to feedback from Nikolai Skrynnikov. I have no idea why the phi_ex and pA.dw^2
parameters were being used in the first place. The model results after the change are identical.

Changed the definition of tex thanks to feedback from Nikolai Skrynnikov.

This was previously defined as tex = 1/(2kex) to be compatible with CPMGFit, but has now been
changed to tex = 1/kex.

The specific_analyses.relax_disp.parameters.loop_parameters() function can now run on a slave.

This is to fix a problem with r21250.

Shifted the optimisation printouts for the dispersion analysis out of the memo.

This improved the ordering of the printed out messages when running on a cluster. Instead of having
multiple optimisation printouts followed by a list of the corresponding optimised values, now they
are interleaved as they should be.

Fix for commit r21247.

Missing import.

Proper handling of the back-calculated dispersion data for the new 'MMQ 2-site' model.
