Removed some debugging printouts accidentally committed in r17734.

The fix of r17733 actually broke Python 2.

The list.__setattr__() method is fundamentally different between Python 2 and 3!

Python 3 fix for the setting of diffusion and alignment tensor simulation values.

The previous code somehow worked in Python 2 but was not formally correct and broke in Python 3.

Python 3 fix for the model-free results file reading tests.

The ordering of dictionaries is different in Python 3, so now these are properly converted from
strings to dictionaries before comparison. This was not happening because of the XML changes from
Python 2.7.3 onwards.

The relaxation curve-fitting system tests are now skipped if the module is missing or broken.

This improves the printouts from the test suite and shows a summary of skipped tests rather than a
pile of traceback messages and errors.

The messsage about skipping the GUI tests due to wxPython being missing is now more specific.

This was being shown for all runs of the test suite when it only needs to appear if GUI tests have
been run.

Added a Python 3 version of the truncated OMP model-free results file.

This was created with trunk which is during the 2.1 relax releases.

Removed the Python 3 byte array hack which should have been removed earlier.

This code is from r17669 which should have been removed at r17712 but was accidentally left out.
Instead of reverting, the code has been deleted as r17669 contained another useful change.

The OMP model-free results file generation script now outputs for any relax version.

Python 3 fix for the Mf.test_latex_table system test.

The latex_mf_table.py model-free system test script docstring contains backslashes, so the raw
string format r"""Text""" is now used.
