core: improved getOrClone + use in chat and widgets_handler:
- getOrClone is now trying to re-use others instances of a widget if they have no parent, and will create a new widget only if nothing is found
- it is now used in widgets_handler's changeWidget
- it is now used in Chat factory, on existing widget
- new host method deleteUnusedWidgetInstances remove instances without parent. It is used by getOrClone.
