Combinator Funnel
The Combinator Funnel is a machine that acts as a cheap, unpowered, specialized version of the 
automatic crafting table when crafting 2x2 or 3x3 squares of the same item. It is mainly used to combine small powder items into full size powder items, or nuggets into ingots.
The desired pattern is selected with a small toggle button in the bottom-right corner of the GUI. It's input slot is on the top, and the output slot is on the bottom, and inputted items can be taken out from the sides, helpful to prevent the funnel from clogging.
