Start work on updating the electrolytic separator. It can output both gases now! Should support recipes as well.
Add Chlorine, do more E. Separator work, including temporary lava/brine substitute. I think it's pretty much finished for now, though maybe it could do with a new model.
Make ComputerCraft modems placeable on energy cubes again. I think it broke when the nice model was added.
Move separator into mek core, let IDEA optimise imports. Hope I didn't screw anything up too badly.
