Machine Extender

[benbenlaw]

would be great if the machine extender could work in other directions as well as up, also supporting mekanism chemicals would be awesome as well

#143 means that mekanism chemicals will be supported as soon as mekanism makes a minor change: mekanism/Mekanism#8411

I would also like to see the Machine Extender work in other directions. (at least downwards)
I play a modpack with multiple multiblock structures, most of them have a single controller and it would be nice to hide the connections below the surface.
