Modifying the function test 'test_read_xyz_internal1()'.

This is Han's patch https://gna.org/task/download.php?file_id=13144 attached to the task
http://gna.org/task/?7404.

The function 'test_read_xyz_internal1()' was modified so that it is more specific to the XYZ file
added to relax and for the new XYZ reader.

A spacer is now used for add_text_sel_element() if no button is present to fill the button space.

The model-free, Rx, and NOE frame main box sizers all expand horizontally now.

The text controls are now horizontally expandable.

Creation of a new system test test_read_xyz_internal1().

This is Han's patch http://gna.org/task/download.php?file_id=13143 attached to the task
http://gna.org/task/?7404.

In order to create a system test for reading the xyz file, a new function
'test_read_xyz_internal1()' has been generated in the xyz/test_suite/system_tests/structure.py. It
is based on the function 'test_read_pdb_internal1()'.

Added a hard coded variable for the size of the graphical part of the analysis frames.

Simplified and localised a variable.

Both SetSize() and SetMinSize() are now used for the main GUI window.

This allows for a proper layout.

Changed the Frame.SetSize() call to SetMinSize() to prevent the main GUI window becoming too small.

Removed a duplicated self.SetSize() call for the main GUI window.
