#1300006 - Add locale besides language name

https://bugs.launchpad.net/mixxx/+bug/1300006

All languages ​​are displayed from the "basic name" of QLocale and this makes that same language names are repeated...
eg. Chinese and Portuguese.
And in this way is impossible discover which one is correct...
-Portuguese of Portugal? Portuguese of Brazil?
-Chinese of China? Chinese of Taiwan?

My suggestion is to add the location next to the language, for example:
QString ("%language (%locale)")
\> English (en)
 \> Portuguese (pt_BR)
