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)
Items can now flow from one chest (or Nore's filter object) to another via the
pneumatic tubes! Thanks to Nore and RealBadAngel for the code.
Note that this mod has to redefine the default chests and furnaces (see
compat.lua) in order to add some new group definitions so that tubes can
appear to connect to these objects.
