Ensure the root part is correctly oriented

This works when the root part's forward axis is at least 30 degrees away
from the node axis (forward (+Z) is towards the VAB north wall, thus
is many parts' ventral side). This means that when the bottom node is
used, the ventral side aligns with the micro-pad's blue diamond and the
starboard side aligns with the red diamond (hmm... that's a bit off
since red is port and green is starboard...)
