Replace the Smart Random Players in the demo game

[Debilski]

Maybe also get rid of the Smart Eating Players. Or at least make them non-suicidal in most cases.

I’m not even sure they should be super smart. But maybe just walk over to the other side and walk around there a little bit without getting eaten is this too much to ask for.

Maybe also invent two cooperative teams. That way they are useless for the students. :)
