limited the number of recipes affected by it - now only the tubes' recipes
are disabled when technic is present. All pipes, pipe devices, and tube
devices are available at all times.
updated the plastic sheet crafting chain to match current homedecor
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 :-)
