1) fts_fuzzy_match has been extended to support wchar_t for a char
type and uint16_t for an index type for the match indices.
2) fts_fuzzy_match has been extended to place a proper stopper character
into the match buffer.
3) Slicer integration now uses the fuzzy match indices for highlighting.
4) Slicer integration now correctly highlights the matched word.
5) Slicer search dialog now sorts based on match AND category.
Further modifications are planned:
1) Matching in local language vs. English: Just show the English variant
if matched in English. Don't mix the two together.
2) Matching the group or category: Continue matching the label.
3) For matches with equal match quality and category sort alphanumerically.
