Update notes for early users
============================

* Property definitions has been removed
* ``[Form|List|Datagrid|Show]Mapper::add`` signature has been updated
* ``FormMapper::addType`` does not exists anymore
* ListMapper now have an ``addIdentifier`` method
* internal Sonata Form Types must be set as second argument of the FormMapper
