Added initial data for testing data from Paul Schanda.

This will demonstrate that there are several possibilities to enhance the r2eff point method.

Bug fix for the storage of the XML structural object in the state and results files.

Previously any objects added to cdp.structure (or any structure object) would not be saved by the
structural object to_xml() method unless the function is explicitly modified to store that object.
Now all objects present will be converted to XML.

Expanded the description of the sequence.attach_protons user function.

This follows from http://thread.gmane.org/gmane.science.nmr.relax.user/1849/focus=1855 .

Fix for the CSA constant equation in the model-free chapter of the manual.

This was spotted by Christina Möller and reported on the relax-users mailing list at
https://mail-archive.com/relax-users%40gna.org/msg01776.html .

Added a redirect for http://www.nmr-relax.com/api/bmrblib-module.html.

This is pointed to by some old Bmrblib news items, so now this redirects to the newer link of
http://www.nmr-relax.com/api/4.0/bmrblib-module.html.

Increased the Gna! news item sectioning depth in the release checklist document.

Updated the minfx and bmrblib versions in the release checklist document to 1.0.12 and 1.0.4.

This is to remove the numpy FutureWarning messages about the '== None' and '=! None' comparisons to
numpy data structures, which in the future will change in behaviour.

Updated the Mf.test_bug_23933_relax_data_read_ids system test to catch the RelaxMultiSpinIDError.

This allows the system test to pass, as a RelaxMultiSpinIDError is expected.

Fix for bug #23933 (https://gna.org/bugs/?23933).

This is the "NameError: global name 'ids' is not defined" problem when loading relaxation data.

The bug was introduced back in November 2014 (r26588), and is due to some incomplete error handling
code. The problem is that the spin type that the relaxation data belongs to (@N vs. @H) has not
been specified. Now the correct RelaxMultiSpinIDError is raised. The 'ids' variable did not exist
- it was code that was planned to be added, but never was and was forgotten.

Created the Mf.test_bug_23933_relax_data_read_ids system test.

This is designed to catch bug #23933 (https://gna.org/bugs/?23933), the "NameError: global name
'ids' is not defined" problem when loading relaxation data.

A truncated version of the PDB file and relaxation data, the full versions of which are attached to
the bug report, consisting solely of residues 329, 330, and 331 have been added to the test suite
shared data directories, and the system test written to catch the NameError.
