Please fix artillery horses dead rate

[LEGIO_Desaix]

Aside from the artillery reverting to fire after ordered to unlimber, I think that train horses die too fast. A couple of shots nearby and all horses fall splattered immediately.

Please INCREASE the fire defence of horses both to counterbattery fire and to muskets fire. Increasing the artillery crew makes some of the men remaining stucked when the battery moves away. But the big problem is atm horses pulling the guns.

Furthermore it seems that the first salvo of enemy battery often (i'd say always) struck a cannon. Round shots are pretty ineffective in vanilla, if we add the train fragility we have a pretty useless artillery (I hate to use shrapnel as they were late period ammos used almost only by brits).

Second tiralleurs in open order are way too resistant to cavalry charges, they should go almost immediately in rout when contacted. This is bringing MP battles to light infantry feast, which was not the case in reality.
