setting up the process for grinder & press

Press i think i might need to do some more work to get it were i want. I
might want to even setup a separate tileEntity as i plan to do armor and
part pressing with it. In which it will require a 3rd item slot for the
imprinting plate. Idea is to provide very cheap part creation as 1/2 to
3/4 the cost of making the item by hand. This way mass production can be
achieved with a bonus over normal production. A few other machines might
be created later when i implement higher tech machines, items, entities,
drones, missiles, etc etc
