Subject: [PATCH] QApplication: Emit paletteChanged signal

This signal was added to QGuiApplication and QGuiApplication::setPalette.
Since this function is static QApplication has its own distinct implementation
which never emitted this signal. This results in items, such as QtQuick
SystemPalette, which listen to paletteChanged to not update when using
a QApplication.
