Generating new user function 'read_xyz()'.

This is Han's patch https://gna.org/task/download.php?file_id=13148 attached to the task
http://gna.org/task/?7404.

The user function 'read_xyz()' was generated in the prompt/structure.py by duplication of
'read_pdb()' and modified accordingly.

Better layout for the base class static text, text control and button addition.

The right hand box in the analysis windows now expands vertically with window resizing.

The results tab now uses the base setup_analysis_element() method to add borders.

The NOE and Rx analysis windows now use the base class build_main_box() method.

Their build_main_box() methods have been renamed to build_left_box() and modified to suit.

Modifying the function test 'test_read_xyz_internal1()'.

This is Han's patch https://gna.org/task/download.php?file_id=13147 attached to the task
http://gna.org/task/?7404.

In the 'test_read_xyz_internal1()' option parser='internal' has been removed.

Shifted the model-free window build_main_box() method to the base class.

Split the auto model-free build_main_box() method into two.

The left hand box is now created by build_left_box(), to reflect the design of build_right_box()
and to allow build_main_box() to be abstracted into a base class method for all analysis frames to
use.

The auto model-free analysis frame now uses the base setup_analysis_element() method.
