Adds a missing check for the case where the eccentricity vector is in the third or fourth quadrant, requiring arg_pe to be negated. Note that this causes an edge case where arg_pe should be 0° but it comes out as 360° because we are not using modulo, but rather adding 2*pi. I didn't want to fix that in this commit because all the calculations in from_state_vector behave the same way. Fixes RazerM#39.
When negating an angle, consistently use mod 2*pi instead of adding 2*pi. This causes 0 to remain as 0 instead of becoming 2*pi.
This was caused by missing check for the case where e ~= 0 when orbits are inclined, thus dividing by the eccentricity resulted in a divide-by-zero. Fixes RazerM#38.
