QAccelerometer should provide user acceleration

QAccelerometer to be enhanced with linear/user acceleration, which means that gravity is filtered off.
iPhone4 API provides acceleration with and without gravity, Android just without gravity
For easy porting and to be able to integrate velocity and distance Qt Mobility must provide both
Naming alternatives include e.g.
1.) bool QAccelerometer: :setLinearAcceleration();
2.) bool QAccelerometer: : setUserAcceleration();
3.) bool QAccelerometer: : setGravityOff();
