Small fix for the GUI analysis deletion method to prevent racing in the GUI tests.

Improved debugging printouts for the Noe.test_noe_analysis_memory_leaks GUI test.

Added a printout to the Noe.test_noe_analysis_memory_leaks GUI test to help with debugging.

Created the blacklisted Noe.test_noe_analysis_memory_leaks GUI test.

This long test can be manually run to help chase down memory leaks. This can be monitored using the
MS Windows task manager, once the 'USER Objects' column is shown. If the USER Objects count reaches
10,000 in Windows, then no more GUI elements can be created and the user will see errors.

Added a debugging Python version check to the devel_scripts/memory_leak_test_relax_fit.py script.

This prevents the script from being executed with a normal Python binary.

Bug fix for the structure.load_spins user function new from_mols argument.

This was incorrectly using the pipe_control.pipes.pipe_names() function to obtain its default values
in the GUI (although this is not currently uesd). The result was a non-fatal error message on Mac
OS X systems of "Python[1065:1d03] *** __NSAutoreleaseNoPool(): Object 0x3a3944c of class NSCFString
autoreleased with no pool in place - just leaking".

The user function class menus no longer have unique wx IDs, as these are unnecessary.

This conserves the small pool of unique wx IDs, as the spin viewer window is created and destroyed.

A small wx ID conserving change - the 'Execute' button in the analysis tabs now uses the ID of -1.

A unique ID is not necessary and is unused.

Another large wx ID saving change.

The ID associated with the special accelerator table that allows the ESC button to close relax
wizards is now initialised once in the module namespace, and not each time a wizard is created.

Shifted all of the wx.NewId() calls for the new analysis wizard into the module namespace.

This will hugely save the number of wx IDs used by the GUI, especially in the test suite. Instead
of grabbing 8 IDs from the small pool every time the new analysis wizard is created, only 8 IDs for
the lifetime of the program will be used.
