get the ElemPillar ItemBlock working.
still fixed some bugs of the multiblock structure:
1.single player world not destroy the old energy units.
2.TE's originCoords and structureSize don't transfer to new TE.
3.structureSize doesn't write to the NBT file.
4.miss assigned the structureSize to originCoords.
