Subject: [PATCH] Fixes #21 - Prevents making oversize stacks in autolathe.

- Previously when making stack'd items in autolathe, it lets you make as big a stack as you have materials loaded, even if it is larger than the maximum stack size for that material.
- Now autolathe recipies remember this, and autolathe respects maximum stack size.
