TITANIC: star control dvector work, replace fn3 with getAnglesAsVect also replace atan2 implementation
fn3 in dvector returns a vector that stores a magnitude, and 2 angles.
The second angle (the z component of the returned vector) was the angle
that the internal vector was between its z and x axis.
This angle was obtained by doing a poor man 4-quadrant atan implementation
and it gave large values for negative x. This has been replaced with the
atan2 standard function.
