Add ability to clear up all windows/widgets

[al2950]

Currently the system relies on the user to clear up widgets and windows before shutting down. (My library instantiates Colibrigui, but not necessarily create widgets directly with it)

Would it be possible to either add some more clean up code in the manager, or at least allow external code to get hold of current windows/widgets so it can clean them up. Eg on unexpected exit.

Suggestion:

1. Create a single root window.
2. Make this window invisible window->setVisualsEnabled( false ).
3. Make sure it uses blank skin (otherwise borders may be applied to its child contents)
4. Everything else is child of this helper window

When you're done, destroy this window, which will recursively destroy all its child content

Layouts are not part of windows (in fact you can allocate them on the stack or with new/delete) thus layouts won't be destroyed by this.

Does this solution work for you?

Yes, in theory this makes sense. Ill give it a go.

Thanks
