"Neutral Generator Needs Tweaking" improvement

I think we should have an option for the random reinforcement generator, to enable random reinforcement placement or disable it and possibly have reinforcement priority levels. This would be in the advanced game options tab (I would suspect it would).

There's not much of a unit difference, but one unit can mean losing a battle when attacking a city.
