Issue description:

Several Issues with auto crafting rockets:

1. JEI won't fill in the rocket recipe in the pattern grid. Understandable I guess since there are 3 recipes. I suggest filling in the one gun powder recipe at least.
2. I manually set the recipe of one paper and one gun powder and the grid correctly showed it would make 3 rockets. I made the pattern but it showed as Invalid Pattern. I turned off the ore dictionary option and made the pattern again and it was valid. I put it in a crafter and tried to make various quantities but after I press the Start the dialog just sits there. The only thing I can do is press Cancel.
