kxmlgui: klanguageoverridesrc format

[René J. V. Bertin]

Hi,

KXmlGui currently uses QSettings in NativeFormat to write klanguageoverridesrc . 
On OS X, that means it will become a binary XML file called 
klanguageoverridesrc.plist, which I personally find undesirable. I think that 
the effect is even larger on MS Windows.

On Linux, NativeFormat and IniFormat are identical and (possibly?) only differ 
in the file extension.

Is there a reason not to replace QSettings::NativeFormat with 
QSettings::IniFormat on all platforms?

R.
