v1.04b (issue): Friendly intercept of moving target stack

[MarkShot]

When you drop one friendly stack onto another friendly stack in another region, you get an intercept situation. However, if the target stack has move orders, then the intercepting stack fails to apply any lead in the current move phase. Thus, the intercept of friendly units only proves useful in two narrow situations:

(1) The target stack is stationary.

(2) The target stack is moving away from (receding) from the intercepting stack.

It does not perform well when the target stack is approaching and passing the intercepting stack.

---

Perhaps, there should some form of lead calculation performed as the predicted paths of both stacks is available at turn computation of the hosting phase.

ok, I have done a fix, but it will have to be tested to see if it improves or worsen the thing:

a) if you target an enemy group, you head toward his current location (no trajectory prediction here, we are in 1775...)

b) if you target a friendly group, you head toward:
i) if the group is not moving, his current location
ii) if the group is moving, the region he is moving into.
