Add test case with URL that consists mostly of numbers

Add a test case for a url that is mainly numbers (e.g. a012.com), and a spoof with similar looking symbols (e.g. aO12.com).

Also adding a spoof that only spoofs the letter part with a different script would be good, e.g. а012 instead of a012 (first a is actually a cyrillic letter а).
