Python 3 fix for the ScientificPython PDB reader unit tests.

The order of the keys returned by a dictionary's keys() method changes randomly in Python 3, so now
they are sorted prior to comparison.

Redesigned the reset user function backend.

This now no only clears out the relax data store, but it also resets the GUI if present. Some of
the reset code comes from the tearDown() method of the GUI tests. All windows but the main GUI
window are closed and the relax controller gauges are set to zero and the log window text cleared.

These changes should allow GUI tests after an error or failure to pass, something which is currently
problematic.

Disabled the initial relax intro print out from the GUI when running the test suite.

This prevents the intro text from appearing in the first failed test.

Fix for the Mf.test_read_results_1_3_v2_broken() system test for Python 3.2.

The object comparison method no longer converts dictionaries to strings for the comparison, as the
string version is different in different Python versions.

Fix for the Mf.test_write_results() system test for the Python 3 versions.

The logic for determining Python 3 versions was broken and the incorrect files was used for Python
3.1.

Python 2.4 and earlier fix for the GUI.

Try-except-finally statement blocks are not supported, so these have to nested in two try statements.

Python 2.4 fix - the unit test runner no longer uses the builtin set() method.

Better Python 2.3 support.

The compat module is now imported at the very start to allow the builtins to be set before any other
imports. The sorted() builtin method is now mimicked and the os.devnull string set for Python 2.3
and earlier.

Fix for the Mf.test_write_results() system test for Python 3.1.

The XML version in Python 3.1 is the old style! Therefore the old results file is being used to
check this Python 3.1 result.

Small improvements to the multiple python version test suite testing script.
