QProcess::startDetached does not support native arguments

The QProcess::startDetached API is missing a way to pass a native command line string like QProcess::setNativeArguments.

Along with all the other requested startDetached features the following API comes to mind:

QProcess p;
p.setNativeArguments("do \"some fancy stuff\"");
p.startDetached();

Where startDetached is a non-static method of QProcess, taking no arguments, but using QProcess merely as "configuration object" for starting a detached process.
