When I attempt to set an item rate, whether in the console or from the chat line, I receive errors.  For instance, if I type:

/itemrate Hammer 0

I receive the feedback:

Crafting Controller: Hammer 0 is not a valid item. Please use the name of the item as it appears in the item list. Ex: Camp Fire

I'd like to make everything except rockets and C4 craft faster, and make these items craft at their normal rate, but I can't get anything to set.  I would just go into the json file and add them there manually, but without any data added, I don't know what format it's looking for in that file.
