Outdated info in documentation of the IWizardFactory class

The information contained in IWizardFactory class documentation page about making system familiar with custom wizard factories is much outdated as since 3.5.0-beta1 release you should use IWizardFactory::registerFactoryCreator instead of putting object into PluginManager's pool with addAutoReleasedObject.
