  are extensible.
* Move the definition of the factories of one editor from the editor to
  its bindings.
* Create the concrete factories by reflection when a FX editor is
  constructed.

* Retain almost all ratings ratings
* Exception: AbstractTextCellDatabindingEditingSupport, whose
  setupFieldAssist() method was removed since
   * it would have introduced a dependency to another package in
     base.ui only because is "FieldAssist" class was referenced in
     the method *comment*.
   * However, this method is only used very rarely and users of the
     class setup up their field assist in createCellEditor() instead.
