TextMenu - Foreground and Background Colors

[lastunicorn]

The foreground color should be used for displaying the menu items. If no foreground color is specified (= null), the default foreground color of the console must be used.

The background color should be used to paint the rectangle in which all the menu (title, items, question) is enclosed. If no background color is specified (= null), the default background color of the console must be used.
