Added Nore's item transport mod and integrated it into pipeworks

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.

Changelog Changelog
--------- ---------
2012-08-24: Added square-ish pneumatic tubes, with their own autoplace code 2013-01-13: Tubes can transport items now! Namely, I added Novatux/Nore's item
(they do not connect to the steel pipes or their related devices). transport mod as a default part of this mod, to make tubes do something useful!
Thanks to Nore and RealBadAngel for the code contributions!
2013-01-05: made storage tanks connect from top/bottom, made storage tank and
pipe textures use the ^ combine operator so they can show the actual liquid
going through the pipes/tanks.
2013-01-04 (a bit later): Made pipes able to carry water! It was just a minor
logic error resulting from moving the water flowing code into it's own file
when I originally imported it. Many thanks to Mauvebic for writing it!
2013-01-04: First stage of integrating Mauvebic's water flowing code. This is
experimental and doesn't move water yet - but at least it doesn't break
anything :-)
2013-01-01: Various minor tweaks to textures, facedir settings, some other
stuff. Changed crafting recipes to account for revamped pumps, valves, etc.
Now requires the moreores mod and most recent git (for mese crystal fragments)
to craft a pump. Added a "sealed" entry/exit panel (really just a horizontal
pipe with a metal panel overlayed into the middle). Also, tweaked pipes to
always drop the empty ones. Revamped pumps so that now they should sit in/on
liquid and be connected only from the top, relegated grates to decorational-
only, added outlet spigot. Got rid of a few obsolete textures. Got rid of
that whole _x and _z naming thing - now all directional devices (pumps, valves,
spigots, tanks) use facedir. Valves, spigots no longer auto-rotate to find
nearby pipes.
2012-09-17: Added test object for pneumatic tube autorouting code, made tubes
connect to it and any object that bears groups={tubedevice=1} (connects to any
side)
2012-09-05: All recipes doubled except for junglegrass -> plastic sheet (since
that is derived from home decor)
2012-09-02: Fixed plastic sheeting recipe. Added crafting recipes for various
objects, with options: If homedecor is installed, use the plastic sheeting
therein. If not, we define it manually. If the Technic mod is installed,
don't define any recipes at all. Also removed the extra "loaded!" messages and
tweaked the default pipe alias to point to something that is actually visible
:-)
2012-09-01: flattened wielded pipe segment.
2012-08-24: Added square-ish pneumatic tubes with their own autoplace code
(does not connect to steel pipes or pipe-oriented devices), then revised their
textures shortly after. Fixed a recursion bug that sometimes caused a stack
overflow. Old pipes were overriding the pipeworks:pipe defintion that belongs
with the new pipes.
2012-08-22: Added outlet grate, made it participate in autoplace algorithm. 2012-08-22: Added outlet grate, made it participate in autoplace algorithm.
Extended storage tank to show fill level in 10% steps (0% to 100%). Added Extended storage tank to show fill level in 10% steps (0% to 100%). Added
