Autoreloaders

[Just-a-Unity-Dev]

Split from #294

Essentially, allow the linked gun to be reloaded from a remote location approx 5-10 tiles away at the cost of a 3s doafter. This is because in the upcoming kinetics rework, I intend for many of the ammo boxes to be shortened in size, so having autoreloaders that just take ammo and stuff it in the linked gun would be neat. They would probably accept any item, and anything that doesn't fit in the gun it just throws out, so yeah autoreloaders would be nice
