new items & recipes

I created some new items (kudos to the guy who created the CataModder tool) and added some crafting recipes.

I wonder what other plastic items we might create... Plastic bags? Plastic jerrycans?

I made the mold roughly the case of a jerrycan just in case we decided to add the ability to craft said jerrycans using it.

I also added a craftable chemistry set. If it is merged, it could be required for most CC_CHEM crafting.
