Extracted nasty case statment from seed method.  It has been moved into a category and styles json file.

This makes it much easier to understand and read or come back to and change later if need be.  All current specs passing.  Going to write some more to make absolutely sure it is working as intended.
Added one more spec to ensure we are setting the proper category for an Old / Strong Ale
