Sided power test: Just for review, don't merge until fixed/agreed upon

Wanted to get your opinion on this. I gave the Wooden power pipes sided RFBatteries, so now when an engine inserts energy it goes into one of 6 separate RFBatteries, which are then drained at a rate proportional to the requested energy into each internal buffer. I'm not sure if this is too much of a mechanics change, but it does fix the problems with energy rendering from the wrong places. (Unfortunately it doesn't allow wooden pipes to power machines yet, I'm not sure how to do that, but I would love to add it)

The math for draining is a bit off, but that will be fixed if this seems like a good idea. Also the energy buffers for each side should be a bit smaller, to compensate for the fact that there are now 6 of them.

This also breaks MJ5 compatibility, so this should at least wait until after Railcraft updates.
