So AIs get:
1) The triangle ships (Fighter, Bomber, Missile Frigate), Mark I-IV
2) Any ship types unlocked by their AI type, Mark I-IV
3) An additional ship type, Mark I-IV
4) Additional ship types unlocked based on AIP, Mark I-IV
5) Two ships types, Mark V (does not unlock Mark I-IV if that ship type isn't unlocked by points 1-4)
Also, I recall another ship unlock happens at 200 AIP, and AIP reducers don't un-unlock the ship type, but what are the other break points for ship unlocks?
