The 'LM63' and 'LM63 3-site' models are now classified as nested in the dispersion auto-analysis.

The grid search for the 'LM63 3-site' model is therefore skipped and the starting parameters for
optimisation are set to those of the optimised 'LM63' model.
Updated the relax results for the truncated CPMG data from Flemming Hansen.

This includes the new results for the 'MMQ CR72' model.  The analysis uses more model nesting.  And
the Grace plots now include the interpolation graphs (hence the plots are now bzip2 compressed).
Updated the NESSY results for the truncated CPMG data from Flemming Hansen.

This now uses the data from all residues to allow for a proper error analysis so the results are
comparable to all the other software.
