AI and city morale improvment building.

[boulugre]

I just noticed something which i think explain to some extent why the AI generally does not perform very strongly, even in higher level of difficulty :

AI does not build the higher level morale improvement building. I guess that they only build them when they reach a negative morale bonus due to population and pollution. As at highest level of difficulty AI gets a significant boost in morale they end up not building them.

This make no sense as those building will benefit your economy regardless of your current moral level. They are actually the most powerful buildings available and should be prioritize by AI as such.

Currently a player who builds all morale improvement will have better economy than the AI, which should not be the case in very hard level of difficulties.
