Bug fix for the failure of the test suite with the loading of Sparky peak heights.

This issue was that the exponential curve fitting saved state file 'rx.save.bz2' could no longer be
loaded. This is because of the complete redesign of 'self.relax.data' which has occurred in this
branch.

Ported r2837 from the 1.2 line.

The command used was:
svn merge -r2836:2837 svn+ssh://bugman@.../svn/relax/1.2

This fixes a bug in the Sparky peak intensity code.

Ported r2837 from the 1.2 line.

The command used was:
svn merge -r2836:2837 svn+ssh://bugman@.../svn/relax/1.2

This fixes a bug in the Sparky peak intensity code.

Fixed a newly introduced bug in the reading of Sparky peak intensities.

The bug was caused by r2798 (https://mail.gna.org/public/relax-commits/2006-11/msg00096.html). The
expected proton and heteronucleus names returned by the 'self.intensit_xxxxx()' functions had been
swapped but the Sparky intensity function had not been updated.

Ported everything from r2732 to r2833 of the 1.3 line. This brings this branch into sync with 1.3.

The command used was:
svn merge -r2731:2833 svn+ssh://bugman@.../svn/relax/1.3

Ported r2831 to r2833 from the 1.3 line.

The command used was:
svn merge -r2830:2833 svn+ssh://bugman@.../svn/relax/1.3

These changes to the relax user manual include an update to the core design diagram and three flow
diagrams describing the steps of model-free analysis (the technique of Mandel et al., 1995, using
AIC model selection and model elimination, and the new model-free optimisation protocol of
'full_analysis.py'.

Ported r2829 from the 1.3 line. This updates the release checklist.

The command used was:
svn merge -r2828:2829 svn+ssh://bugman@.../svn/relax/1.3

Changes to the model-free optimisation protocol diagrams (relax manual).

Arrows have been added to indicate where to start with the analysis.

Added three flow diagrams to the relax manual describing the steps of model-free analysis.

The first diagram details the steps of the model-free optimisation protocol introduced by Mandel et
al., 1995.

The second presents the changes which occurred with the introduction of AIC model selection,
model elimination of failed models, and the use of all diffusion tensor types.

The last diagram presents the new model-free optimisation protocol encoded into the
'full_analysis.py' sample script (which is described in a manuscript which has been submitted for
publication).

Updated the relax core design diagram in the development chapter of the manual.

The user functions were being referred to as macros. The change of name from user function to macro
occurred years ago.
