[qt] Filter collates accents (Unicode NFD) (#4380)

Browse Source 
Now "POKEMON" and "pokemon" are the same, and search's no longer case sensitive.
Maybe we could transliterate? But that would require icu which is a bit overkill.
Main point is to be able to search "Pokemon" (accent on 'e') without actually typing the accent
