Fixing the AI money script (preliminary tests)

[Wolfshart]

One thing I did notice on my Romani campaign and an unmodified script is that the Carths naval power seems to be limited by the huge Rebel/pirate naval presence in the Med. Only after I take my own navy and destroy a good portion of the rebel navies does the Carths navy get to do any thing appreciable. Are those powerful rebel navies seeded throughout the Med to hinder the AI or the player? To me it seems like they are limiting the AI to much.
