Fix nature_of_code/chp_01_vectors example #885

When the distance vector between the mouse coordinates and Mover is zero, the calculation results in NaN as it tries to normalize() it. (Blank screen is displayed.)

I found normalize_or_zero() in the docs and this would be great alternative for the case.

Looks good to me and should be merged soon.
