Sets whether to ignore unknown options or not. If an argument is
ignored, it is left in the argv array after parsing. By default,
OptionContext.parse treats unknown options as error.
This setting does not affect non-option arguments (i.e. arguments
which don't start with a dash). But note that GOption cannot reliably
determine whether a non-option belongs to a preceding unknown option.
