Pre-GIMP-3.0 code logics would re-allocate several GimpMenuFactory or GimpUIManager for no good reason. While it was still working with old GtkAction code, with our new GAction-based code, we were ending up overriding an action with a new version of the same action, while keeping reference to old actions. This made for discrepancies of the enabled or visible state of actions. The new code keeps singleton of some objects and references to already registered GimpUIManager or GimpActionGroups objects and make sure no actions with the same name are created twice.
