Issue description: When setting a patter to craft 9 charcoal into a block of charcoal, it automatically selects the Chisel version of block of charcoal. This type can't be used as fuel, and also cannot be crafted back into charcoal. This is not really RS's issue, but it would be helpful to be able to manually specify the output for some non-processing patterns.

What happens: The pattern grid automatically selects the first result of a non-processing recipe when creating a pattern

What you expected to happen: What I'd suggest occur is that it's current behavior stay the same, but give the ability to override the output when creating a pattern.

Steps to reproduce:

1. Go to a pattern grid with a blank pattern ready
2. Put 9 charcoal filling each black spot for a non-processing recipe
3. Pattern grid fills in the output
   ...

Nope!

You have a recipe conflict then. Some mod is overriding the charcoal block recipe. Not an RS problem.
