Pet Collectors: Start farming mats

In 3.3.3, Blizzard is making two engineering pets, open to everyone. Using a script I've developed, I've put together all the mats you'd need to build each. It will break down each item into key components.
For example, you could just buy the "Big Iron Bomb". Or you could have the engineer build it. To build it, they'd need an iron bar, heavy blasting power and a silver contact. The Silver contact requires a silver bar, which a miner can be make from Silver Ore.
