Ensure that single character errors don't give rise to legal inputs.

[el33th4x0r]

No two words on the list should be within 1 Levenshtein distance of each other. That way, a simple transposition of characters or a single character addition or deletion typo won't give rise to another legal input. For instance, "ionic" and "tonic" are both on this list. They should not be.
