Made additional check in sequence reading, that "nan" values are skipped.

Added systemtest relax -s Relax_disp.test_paul_schanda_nov_2015 -d.

This will cathc the loaning of "nan" values.

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.
