Fix for racing in the Dead_uf_pages.test_mol_create() GUI test.

The GUI interpreter object flush() method is now being used after each user function, as they are
operating asynchronously!

The GUI test _execute_uf() base method now allows the wizard run() method to be executed.

This gives a better work out of the user functions and matches more closely to what a user will
experience.

Fixes for the pipe name in a number of the OMP final_results_trunc_1.3*.bz2 results files.

Deleted a ton of now unused and useless code from gui.analyses.results_analysis.

Print statement conversions to function calls for Python 3.x.

All non-debugging print statements are now function calls. The debugging printouts have been
deleted.

Removed some debugging code.

Fix for the State.test_load_state_no_gui() GUI test - the final_results_trunc_1.3.bz2 file has been renamed!

Bug fix for the model-free specific analysis - the Dr diffusion tensor parameter is now defined.

Complete redesign and creation of the 2nd version of the relax XML format for save and results files.

This is a BIG set of changes! It includes the following:

- The XML files now have the new 'file_version' attribute within the 'relax' XML element. This is
now set to '2', and if unset it is assumed that the file version should be 1.

- The file_version integer value is now propagated through all of the from_xml() methods so it can
be passed into the data.relax_xml.xml_to_object() function. This prevents a mixture of v1 and v2
being assumed for different parts of the XML.

- An XML namespace fix - the xmlns="http://www.nmr-relax.com" attribute is now finally visible.

- The data.relax_xml.object_to_xml() function has been added for creating the new relax XML syntax.
This will handle and convert many more basic Python object types into IEEE-754 byte arrays, for
example lists and dictionaries of floats, or numpy vectors and matrices. This function is now used
throughout the code base for converting Python objects to XML.

- The data.relax_xml.xml_to_object() function has been expanded to match the functionality of
data.relax_xml.object_to_xml().

- The Python object XML elements now have the 'type' attribute indicating the Python object type.
This is important for the processing of the file, especially for handling all types of numpy
structures.

- The Python object value is now stored in a sub XML element called '<value>'. If it is a float, or
is a simple type which contains floats, then the sub XML element <ieee_754_byte_array> is created
for storing a full precision version of the floats. The <ieee_754_byte_array> value will always
trump the <value> value!

- The v1 and v2 of the format together with the pre- and post-Python 2.7.3 XML toprettyxml() changes
are now represented as test_suite/shared_data/model_free/OMP/final_results_trunc_1.3*.bz2 files. A
5th file is added to test the IEEE-754 conversions by corrupting many of the floats. Each results
file is tested with 5 new model-free system tests.

Fix for the truncated OMP model-free results file - the pipe name was incorrect.

This was only recently broken.
