Replace deprecated call to get_background_color by get_property and a following check if the property is a color (check is needed because gtk does not know if value really is color)

The functions are not officially deprecated in lokis version of gtk. They are deprecated in newer versions because the "background" of an object does not necessarily have to be a color (thats why I check for the returned property to be a color.)
