No sure were that came from

Looks like my computer picked up some very old code and included it on
push.
setting up tank for IConnectionProvider

for now I will just use it for connection rules for rendering, and trade
processing. However, in the future i might use this with the path finder
to make a more uniform movement of liquids in the connected tanks. Might
even have them update all as one entity instead of each one at a time.
Though that will take some time if i set it up just like the UE wire's
network. As i will have to make sure that the liquid always travels to
the lowest tank first, and saves to the lower tanks. Which means that
i'll end up storing the tank's Y pos or getting it during
saving/loading/processing.
Some cleanup for the tank's render

Still haven't fixed that odd error with the connector rendering on the
wrong face. Though the plan is to remove the connector render as you
can't see it past the pipe.
