Switch to Levenshtein distance for spelling suggestions

We've noticed this making an improvement for some particularly
questionable spelling suggestions, even in cases where the default
distance metric (Damerau-Levenshtein) assigns the same distance score.
In such cases the DL and L distances normalise to different values,
and that seems to be what tips the balance.
