The KeyboardPlugin will now track the key code and timestamp of the previous key pressed and compare it to the current event. If they match, it will skip the event. On some systems if you were to type quickly, you would sometimes get duplicate key events firing (the exact same event firing more than once). This is now prevented from happening.
