[Open] Battle Calc does not account for bombard limits
a very minor thing: the battle calc doesn't account for limiting the number of bombards based on the number of attackers. So on maps where you only get one bombard per amphibious attacker, if you go to battle calc and put in 1 inf and 7 battleships bombarding, it'll show results as if all 7 bombards work rather than just the 1.
It'd be nice to fix to help with people forgetting which maps allow unlimited bombards and which don't. but a rather low priority, since they'd uncover it pretty fast when they actually play the map.
