Improvements to the structure.load_spins user function definition.

The spin_id arg now uses the special 'spin ID' arg type for the spin ID GUI input element.

A number of improvements for the spin ID GUI input element.

This includes:

- The fix of r16541 for the use of SetValue() for strings not in the list of choices.

- Defaulting the choices to ['@N', '@C', '@H', '@O', '@P'] if not supplied.

- A tooltip white space fix.

- Removal of the None element in the list of choices, as this is not a read only box.

Increased the size of the spin loading wizard to match that of structure.read_pdb.

Missing import of wx.grid.

This worked before as the import was in the ancient gui.analyses.results_analysis module, but this
was deleted at r16535.

The Value GUI input element UpdateChoices() method now handles non-selection strings in the ComboBox.

The SetStringSelection() method is now only used when the combo default is one of the choices, and
SetValue() when not in the list of choices.

Fix for the GUI user functions - a call to update the parameters no longer wipes out the current value.

This is for ComboBox elements where a string has been input rather than one of the choices selected.

Decreased the amount of waiting time in the GUI interpreter flush() method.

This will allow speed ups in certain parts of relax (for example some GUI tests).

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.
