Add patch from Mario Luzeiro to 3D viewer. Fix a serious issue due to duplicate ID used in menus and toolbars between sub-applications, related to wxUpdateUIEvent events loop.
wxUpdateUIEvent events can be sent to parent frames, when opening a menu in a child frame, if parent and child frame share same ID fro menuitems (or tools)
The wrong menuitem can be used in some cases ( because there are more than one menuitem with the same identifier), by a wxUpdateUIEvent event function run in a parent frame.
