Fix AI status screens

[NateTheSquid]

This is a suggestion, definitely, because it's a feature right now. AI status screens currently show a generic blue AI face, with the mood thing that the AI has chosen, but ignore the AI's set colour. Why not just make the screen crop an image from the AI's core, and dump that on each status screen? Maybe set a smaller version of the AI's core sprite as it's own sprite and put those on the AI status screens.

Would also allow things like static AI's from death, the malf AI skin thing from that achievement to show up on status screens. Maybe even make it a toggle for the AI? Probably not
