Preliminary checks

• I've checked that there aren't other open issues on the same topic.

Describe the problem requiring a solution

At the moment the current retreat decision making is done for the current unit. However, if the next unit to move is still friendly one the retreat decision should be delayed to the very last.

Describe the possible solution

Improve retreat decision making by possibly make more losses for the enemy if the next unit is still the friendly one.

True, but there are cases that can cause creature to skip his turn (negative morale). They should be accounted for decision making.
