Uzbegistan ICAO airport code changes

[pkzc]

The Tashkent airport ICAO code has recently been changed from UTTT to UZTT. After manually changing the airport code for the weather applet (dconf key /org/mate/panel/objects/clock/prefs/cities) I am receiving again weather report from Tashkent.

The other Uzbegistan ICAO codes have also changed in a similar manner.
