#538 ASCII-based (?) sorting in Xiphos

[Matej Cepl]

Sort in Xiphos is most likely ASCII-based or something, certainly it doesn't follow proper Unicode. For example, my native language is Czech (that's "Čeština") and I would expect it to be sorted between "C" and "D". However, I have to always look for it somewhere between Hindi, Urdu, or whatever languages they are (see attached screenshot). I am certain Qt-based application can do a way better than this.

done in -r4934, replaced strcmp() with strcoll().
i expect to put out a new release sometime this month.
