title: PyQt4: QFileDialog and QFontDialog localization
body: <p>Subj: is it possible? For example, can I translate <code>QtGui.QFileDialog().getSaveFileName()</code> button "Save" to "Conservare", and "Cancel" to "Ignorare"? Is it possible to create my class based on <code>QFileDialog/QFontDialog</code> without inventing a velocity?
  Someone said that these functions will be always translated, depending os system locale. Don't believe, my Russian version of OpenSUSE says that it is a lie. :-) And Russian Windows 7 has a such behaviour. All strings which I see on my systems are English. I'm not a nationalist, but I want to use strings in other languages. :-) Thanks!</p>
