sonic_screwdriver recipe doesn't work in mineclone-like games without mesecons_materials

[programmerjake]

it should probably use mat.insulation instead:

technic/technic/tools/sonic_screwdriver.lua

Lines 79 to 86 in 32f1d5a

	minetest.register_craft({
	output = "technic:sonic_screwdriver",
	recipe = {
	{"", mat.diamond, ""},
	{"mesecons_materials:fiber", "technic:battery", "mesecons_materials:fiber"},
	{"mesecons_materials:fiber", mat.mithril_ingot, "mesecons_materials:fiber"}
	}
