Split up the r2eff_values.bz2 save file into the results files for each data pipe.

This is for Flemming Hansen's CPMG data truncated to residues 70 and 71. This is to simplify the
system tests which use this data.

Updated the NESSY log from the Hansen CPMG data of residue 70 to remove the NESSY errors.

These were removed with the commit r1090 to the NESSY trunk.

Updated the NESSY results for Flemming Hansen's CPMG data for the R2eff values with high precision errors.

A file containing the log or printouts from NESSY has been added for reference.

A script has been added to create the NESSY input for Flemming Hansen's CPMG data.

Created the relax_disp.nessy_input user function front and backends.

This user function takes the data in the relax data store and creates a NESSY save file to be opened
within NESSY. The backend is the new specific_analyses.relax_disp.nessy module. For the GUI
frontend, graphics for icons and the wizard have been taken from the NESSY repository file
pics/nessy_new.png@r1088 in the trunk.

The relaxation dispersion loop_point() function can now return the reference point.

This is enabled via the skip_ref argument.

Removed the '_trunc' part of the nessy_results directory from the NESSY final save file.

The CPMGFit script for Hansen's CPMG data now starts with the high precision error r2eff_values.bz2 file.

This ensures consistency between comparisons between relax, NESSY, CPMGFit, etc.

Created a script to calculate the R2eff rate errors extremely precisely for Hansen's CPMG data.

This uses 1 million Bootstrap simulations for calculating the errors. The 'r2eff_values.bz2' is
saved after deleting the spin specific r2eff_sim structures so that the file drops from 388 Mb in
size to 7.3 kb.

Updates some scripts for the spectrometer.frequency user function change.
