Subject: Add digilines support to autocrafter "on" and "off" messages turn it
 on or off, "single" crafts one item, and sending nested tables in the shape
 of the crafting grid sets the craft. Example message: {
 {"default:wood","default:wood","default:wood"},
 {"default:wood","","default:wood"},
 {"default:wood","default:wood","default:wood"} }
