Adds vanilla-themed automatic workstations similar to the crafter.
Smither
An automatic smithing table.
All input slots can be separately disabled.
Outputs a comparator signal of 1 for every input slot that has an item in it or is disabled.
When it receives a redstone signal it ejects the result obtained from the input slots. By placing another container block in front of it will make it eject the result into that container.
Items can be put in it with blocks like a hopper, dropper, crafter, another smither, etc.
