Change NJInputAnalog so magnitudes of subactions are always positive (e.g. -1 magnitude is 1 on low 0 on high, rather than -1 on low and high). Change NSInputs so buttons have a magnitude 1 when pressed, allowing them to also control the mouse. Allow mouse movement speed control.
Improved analog support for scrolling, and allow speed adjustments.
Mouse mode toggle creates really confusing situations right now, disable it.
