Changes

* {{Code|strings:levenshtein("flower", "lewes")}} returns {{Code|0.5}}

* In the following query, the input is first normalized (words are stemmed, converted to lower case, and diacritics are removed). It returns {{Code|1}}:

let $norm := ft:normalize(?, map { 'stemming': true() })

return strings:levenshtein($norm("HOUSES"), $norm("house"))
