Add an AI aggressiveness slider

Add a slider to game creation that can up the AI aggressiveness, the only way I can see losing is if the AI attack me early game causing me to build more ships and upgrade more military than eco or just destroy me if I don't build enough.

I play on endless and I know their is a bug with AI not building bigger ships, I also know that if you put pirates on hard this kind of solves this problem but then the AI time are gimped aswell. 

Maybe a setting where the pirates don't attack AI?

A setting where you can start the game with 2 factions perminantly allied?
