Generating new user functions load_xyz() and __parse_models_xyz().

This is Han's patch https://gna.org/task/download.php?file_id=13247 attached to the task
http://gna.org/task/?7404.

New user functions load_xyz() and __parse_models_xyz() were generated in

Generating new system test 'test_read_xyz_internal2()'.

This is Han's patch https://gna.org/task/download.php?file_id=13246 attached
to the task http://gna.org/task/?7404.

The new system test was generated in test_suite/system_tests/structure.py for
reading a xyz file 'SSS-cluster4-new-test.xyz' with multiple models.

Modifying test_suite/shared_data/structures/Indol_test.xyz

This is Han's patch https://gna.org/task/download.php?file_id=13245 attached to the task
http://gna.org/task/?7404.

In the test_suite/shared_data/structures/Indol_test.xyz 0.00000 after the molecule name was removed.
The reason for that is because in a typical xyz file the second line is just the molecule name.

Fix for a variable name.

Missing import.

Missing import and fixed the initialisation of Wiz_panel.

The GUI and interpreter objects are no longer passed into Wiz_panel.

This is only for the user function specific classes, and is performed in UF_panel instead.

The value.set() GUI user function now uses the new wizard.

The dialog ShowModal() and Destroy() methods are now executed by the wizard run() method.
