Make pods have charge for their weapon

[Dickles]

I don't think pods have any ammo (except grenade pods). I think they should need to recharge after firing a lot; I don't mean it should be limited severely, I like pod fights and stuff. I'm mostly thinking about blob. Pods can pretty much make a wall of death for blobs and never have to stop until there's a reflection tile up. It would be nice if they had to take a break after a bit to recharge somewhere.
