Consider a method for the user to further customise "about" content. Add an "extra" field to AppAboutInfo that is
a dictionary. Key: A string for the name of a tab in a notebook shown on the about dialog. Value: HTML formatted string to
display in tkXHTMLViewerWidget, when the Key tab is selected. Examples would be to have "authors", "components", "licenses" tabs.
By default, the "extra" field would contain an empty dictionary, and then no additional notebook tabs, beyond the default "About"
would be created.
