Missing Sprite: Dwarven Mining Vendor

Created by: Kurfursten

The mining vending machine is missing a sprite for the broken state. I know that @dylanstrategie was behind the change and seems to have an interest in spriting now, so I think he might have fun with this one.

For the uninitiated, vending machines can be broken by an EMP, blob, bomb, or 2% chance on kick.
