autocrafter, nodebreaker, deployer, and made sure each item will only
initiate a connection to those sides which can accept such. Fixed
various autorouting bugs as I ran across them. Autorouting for various
devices is now:
filters: left and right sides only
nodebreaker, deployer: back only
autocrafter: all six sides
chests: top, bottom, left, right, back (not front)
furnace: bottom, left, right, back (not the top or front)
