The element_string_list() wizard method now has all arguments converted to keyword args.

Abstracted out most of the String_list wizard element into the List base class.

This will allow different list types to be easily added.

Fix for the wizard GetValue() and SetValue() methods.

The GUI elements are in the self._elements dictionary!

The bmrb.citation GUI user function now uses the new wizard page string list GUI element.

Completed the wizard string list GUI element.

This control opens a dialog consisting of an editable ListCtrl that the user can input the text
into.

Added the edit-rename Oxygen icons to the paths module.

Added the edit-rename Oxygen icons.

Created a new String_list wizard GUI element class and associated element_string_list() method.

This special object is currently very similar to the input_field() object, but is set up as a class
in the gui.wizard_elements module. The wizard page element_string_list() method has been added as
the interface for adding this element to a wizard page. This method stores the String_list element
in the wizard page _element dictionary.

Created a new infrastructure in the wizards for handling more advanced GUI elements.

The _elements dictionary has been created to store the full GUI elements within the wizard. The
GetValue() and SetValue() methods have been created as a front end to the specific GUI element's
equivalent methods.

The Mf.test_write_results system test now checks for the ancient PyXML.

This ancient version from 2004 which should be eliminated, if installed, causes the toprettyxml()
changes in Python 2.7.3 to be overridden.
