The structure.load_spins spin_id arg no longer defaults to '@N'.

This was introduced at r16545, but causes many test suite failures!

Fix for the Test_spin.test_name_argfail_spin_id() unit test for the spin.name arg rearrangement.

Converted a few user functions to use the special "spin ID" arg type.

Converted the structure.vectors spin_id arg to the special "spin ID" type.

This is to improve vector loading in the GUI.

Increased the size of the unit vector loading wizard in the model-free analysis.

This now matches the structure.read_pdb user function size and allows it to fit!

The min length is now handled much better in the Combo_list GUI input element.

The GUI user function object create_wizard() method now returns True upon success.

This is needed for calls to these objects!

The GUI user functions now called by the results viewer window now have the parent set to this window.

The GUI user function page update_args() method now has a docstring and returns True when successful.

Rearranged the spin.name args and converted the spin ID to the special spin ID type.
