Mortar Truck/Pre 1.3

==Overview==
The Mortar Truck is another take on artillery, and is functionally similar to the Light Artillery and Mortar. The only difference being the Mortar Truck deals more damage, has more HP, and also an infinite amount of ammunition.
The Heavy Mortar weapon of the truck deals 100% damage (45 DMG) in the target square, and 25% damage (12 DMG, rounded up) in the four adjacent squares. These values are modified further by the target's resistance to explosives, and whether the shot is deflected/critical.
