Try to fix energy overflow

[D-Cysteine]

I think I've seen a few reports of the Ender IO staff of traveling and staff of teleportation somehow getting set to IIRC, near Integer.MIN_VALUE amount of stored energy. Reading through the code, the only way I could see for this to happen was if receiveEnergy or extractEnergy was called with a very negative number.

If I'm right about the cause, then this PR will fix the symptoms for Ender IO, but it won't fix the underlying issue that we have code somewhere which occasionally overflows and calls receiveEnergy or (less likely) extractEnergy with, I'm guessing, a value near Integer.MIN_VALUE, and any other mods that contain subclasses of ItemEnergyContainer may still be affected by the issue.

I don't know much about mix-ins, but we could also try putting these checks directly into cofh.api.energy.ItemEnergyContainer.

Code looks ok. But for the qeustion about a general fix I'm not able to provide an answer, need to check someone else probably.
