A better crafter?

To add functionality to copper, I suggest being able to make a “copper craft template” for the new crafter.

It would happen like this:
1) Craft the template,
2) Place the craft in the crafter,
3) "Save" the craft in the template using a new interface.

This will block unwanted items, make the new redstone block easier to use, and add a new useful function to copper!
