Inversion of status of little cube in BlockDetailed.

[lipki]

This bug is revealed by the last change made on the Chisel tool in Stair mode.

This bug is caused by the use of : TEDetailed.Packet_Update
I believe.

TEDetailed - line 122

if (packetType == TEDetailed.Packet_Update) {
            int index = nbt.getInteger("index");
            data.flip(index);

data.flip(index);

"flip" rather than "set", there is a reason for that ?
