Artillery Wagon Mk2

Adds an Artillery Wagon Mk2, which is like the normal artillery wagon only it has an equipment grid in it and more HP.

Inspired by and compatible with the mod Battle Wagons https://mods.factorio.com/mod/Battle_Wagons

If you have Battle Wagons installed, you can use its Battle Laser inserts in an Artillery Wagon Mk2 grid. My mod also makes Battle Lasers compatible with Power Armor Mk2 and Spidertron grids, and also with Power Armor Mk3 grid from Rampant Arsenal if you have that mod too.
