Roan Kattouw b7ee30d4e4 Enslave dm.Surface to dm.Document
* Replace surface 'transact' event with 'documentUpdate' event
* Have surface listen for all document transactions and update selection
  as appropriate (as well as emitting 'documentUpdate')
* Implement change() in terms of setSelection()
** Queue 'contextChange' events so contextChange is only emitted once
** Use this.transacting flag to prevent setSelection() (which is called
   because the model emits transact events) from doing too much
** Behavioral change: lock/unlock now emitted separately for
   transaction and selection changes
