Stage1.continued: Introducing partial emulated MotionPlus+Nunchuk support, allowing us now for instance to get ingame on RedSteel2. However dont expect too much yet, since this is not completely finished. Wii Sports Resort with mp+nunchuk won't work yet and input from the nunchuk passed through the motionplus does not work properly either. Apart from that Stage1, is almost done.

Browse Source 
Just minor stuff that needs to be finished: Dummy motionplus data needs to be kept dynamic(just like wiimote accel data), or it might cause disconnects after some time. Furthermore, there are 1-2 remaining register writes that have to be understood and emulated.(e.g. 0x00F3/F4). In the end just minor stuff. I'll address that in my next commit.
