Translate keycodes of undefined Keys

Use a test that sends both defined and undefined keys to WD (see https://code.google.com/p/selenium/wiki/JsonWireProtocol#/session/:sessionId/element/:id/value for the list of defined Selenium keys):

# key up
elem.send_keys(u'\ue013');  
# key undefined
elem.send_keys(u'\ue088')

Use a test app like this one

Rectangle {
    id: button
    objectName: "button"
    width: buttonText.width + 20
    height: 30

    Text {
        id: buttonText
        objectName: "buttonText"
    }

    Keys.onPressed: handleKeyPress(event);

    function handleKeyPress(event) {
        console.log("key press " + event.key);
    }
}

Observe in the test UI the KeyEvent received are:

# for key up
16777237
# for undefined key
57480

Expected

# for key up
16777237
# for undefined key
16777352

The offset to Qt key should be applied for undefined keys
