Created by Jonathan Mace
This class wraps a Readonly_Textbox in a scrollable window, and adds
a combobox.
The combobox is populated, externally, with the names of
articles which can be selected.
If an article is selected in the combobox, the readonly_textbox will
be set to display the newly selected article.
The articles are loaded using IO_Manager
