Stage1: Introducing MotionPlus as emulated extension, allowing us to boot games that require the MotionPlus itself.

I also already implemented most of the needed data structures and datareport handling for the motionplus-nunchuk passthrough mode, which I'll add up next as well.

Wii Sports Resort is now bootable by just using an emulated wiimote (only working under the old wiimote plugin atm,
I asked billiard to port my commit into his plugin since he knows his plugin better than me and its less work for him than for me,
I kept most parts of my code in modules to simplify that task).

Upcoming stage2: Faking the motionplus on the fly on real wiimotes, that means you will be able to play, e.g.  Redsteel2 with a real wiimote and nunchuk or wii sports resort with just your real wiimote.
and nunchuk, but w/o the need of having a real motionpluscontroller connected. The new Zelda 2010 will benefit by that, since it will require a motionplus controller.
