artillery and ship bombardment improvements

[upyr1]

Some ideas to improve artillery

select ammo type- smoke, AP, HE, and guided.

On the zone radius I would like the minimal size to be the specific pieces' CEP.

The line from the gun to the point being shot at, should change color to indicate if you are trying to fire something out of range.

Unless it is already being done but I'm not setting it up FACS and JTACs should be able to call in artillery 

Next on ships- since we should get battleships and other WWII ships we need an option for a broad side.
