Females shouldn't attack military units unless ordered to

[Kieran P]

Females were given an attack so that they could kill animals.

But now they attack military units automatically.

This should be fixed. Females should run away from attackers unless told to fight them.

[Kimball]

But they need to attack military units if tasked on them - just to clarify.

(In [9010]) Make non-combat units flee when under melee attack, and not attack enemies automatically. Fixes #703.
