MPexperiments

This branch is now adapted to the latest version of MPcalibration in libxwiimote branch.
With this patchset the wiimote can now be used as gyro-mouse on any machine.

I use KeyB as left-mouse and KeyA as right-mouse with an MPCalibrationFactor of 25 and
MPNormalize of 0:300:700 as startvalues (got them from xwiishow)
