xmlui: improvments to prepare parameters: - added missing implementation: JidsListWidget (just a simple ListWidget for now), IntWidget, TabsContainer - _xmluiOnChange implemented for StringWidget, PasswordWidget, IntWidget and BoolWidget - added post treatment handling, as it is needed to adjust TabsContainer height - a "save" button is added on params
