Improving gyro cursor accuracy

IR is hidden at < -0.25 and > 0.25 when gyro input is active because the horizontal cursor is disrupted by IR

Pitch is calculated from IR when gyro input is active because a vertical cursor will sometimes drift to center without pitch

Separating IR and gyro sensitivity because that allow more precise control

Adding fast gyro modifier to cursor input
Emulating acc g-forces from gyro values, etc.

because that's expected by some programs

Adding option to settle gyro if the Wiimote has been still for a while

Adding manual control of the fast gyro mode because it increase control precision

Adding IR hide modifier because it's useful with gyro input
Adding toggle keys for binary settings
