Tomasz Pakuła 529ed102fc Translate conditional effect direction instead of hardcoding it to 0 
Provious code wrongly assumed that direction is not an important part
of conditional effect. Moreover, if there's need to hardcode polar
direction, the default should be 0x4000 (north).

For one axis affects, a direction of 0 means complete lack of force, if
a FFB-enabled device takes direction into force calculation. A sine function
graph can be used to represent the resulting forces where X is the input
direction and Y is the force multiplier (360 degrees equals to 1).

This fixes conditional effect playback on Moza Racing devices, which do
not ignore direction field.
