This adds new AI handicap, H_DANGER. It causes AI to always cosider
all it cities to be in grave danger. This causes it to spend some
resources to unnecessary defense instead of expansion. Handicap is
given to novice level AI. Maybe it should go in for easy AI as well?
Plan is to commit this also to S2_1.
