Recruits Reborn

Five weapons: battering ram, catapult, onager, cannon, and mortar. They are crafted (recipes in the game and in data/recruitsreborn/recipes) and placed using the PCM on the ground. The cannon and mortar can only be placed by a faction that has already trained an artilleryman.
Calculation: the weapon fires only when your fighters are nearby, within 7 blocks. The catapult and onager require an engineer; the cannon and mortar require an artilleryman.
Ammunition: the catapult and onager are loaded with cobblestones, the cannon and mortar are loaded with cannonballs (iron + gunpowder → 2 balls). The ram does not require ammunition.
Orders: a new group “Siege Weapons” has appeared in the menu (R), number 8. It supports movement, “Fire on Ready,” “Do Not Fire,” and a new order “Attack the Target.” To use it, aim at the block before the menu is opened.
Shelling: when “Shell the target,” the guns fire 8 shots at this point, and the rams move towards it and strike.
Breaking blocks: projectiles and rams break blocks, but only those that are soft enough. Obsidian and bedrock are indestructible. This is disabled by the siegeBlockDamage setting.
Safety: explosion
