Subject: [PATCH] Do not perform neighbour updates when using debug stick
CB blindly drops any update flags when recording block modifications,
this causes the debug stick to blindly update neighbouring blocks on usage
in order to control this, we will special case this item, however, this
ideally should be fixed by recording the actual update flags used,
but will induce ABI breaks...
This patch also maintains the behavior of the BlockPlaceEvent, this
behavior will NOT be guaranteed in the future, however.
