Ammoboxes
Adds supply boxes to supply trucks. Based on Valour mod.
There are two types of crates. The first type (little one) is used to resupply infantry guns, AT launchers and mortars. The second (bigger) type is used to resupply artillery, but also can be used as the first type crate. Moreover, the mod activates auto regeneration of a paradrop crate.
Sandbags and mines added to supply trucks as well.
