BUG with IC2EXP Block Cutter

[gonglinyuan]

IC2EXP Block Cutter has a property called 'required hardness' for every block cutter recipes. But when we tried to add recipes into the block cutter with MineTweaker-3.0.10B, we couldn't find anywhere to put this value, 'required hardness', into the recipe. Therefore, the 'required hardness' of the added recipes became 'null'. And the recipes became impossible to use.
