remove obsolete qudevhelper and adopt mouse and touch plugins
The QUDevHelper class is now replaced by QUDeviceHelper class. All evdev input plugins are using the new udev helper now to enable hotplugin for keyboard and mouse input. EvdevTouch plugin still only uses the first detected device by udev, this cannot be tested on my side, due to the lack of multiple touch input devices.
