light gun reload on boxes correct powder

fixed and put an upgrade update on the aftermarket coilgun as it wasn't swapping loader base.

ammo boxes follow new vanilla changes. 2 handed ammo boxes may still be placed on crate shelves and makeshift shelves.

Light gun ammo slows user when carried

vortex cells combineable.

forgot upgrade for previous floppy volley gun turrets.

volley gun had a huge number of issues, all fixed.

volley gun had wrong damping

Added the Volley Gun, a five barrel chaingun variant that fires all barrels at once and conventionally reloads them. Has roughly half the fire rate but does not need to spin up and the locked chambers increase velocity slightly.

slight nerf to autocannon fire rate, consumes more capacitor per shot. Intention is still however to make it efficent to run with discharge coils or coilguns etc which have a higher draw due to not having a chemical charge component.
