DataWord

[nevgeny]

I think this is so strange.

ethereumj/ethereumj-core/src/main/java/org/ethereum/vm/DataWord.java

Lines 257 to 261 in b2bdc82

	public DataWord bnot() {
	if (this.isZero()) {
	return new DataWord(ByteUtil.copyToArray(MAX_VALUE));
	}
	return new DataWord(ByteUtil.copyToArray(MAX_VALUE.subtract(this.value())));

Can we use byte array instead? I can make pr.
