Merge Moo0's data flag for distr.
Also added data flag to //count.
  //count -d 35 will now only search for white wool.
  //count 35:5 will only search for green wool.
  //count 35 will work as normal.
  //count 35:-1 will also work.
Merge korikisulda's butcher brush.
Additionally made it work with //butcher flags (added as an argument)
as well as respecting the max butcher radius if the player has the permission.
