[Chameleon] Close popups when main window closes

[Berend Veldkamp]

Bart,

Thanks for the link.

I just found out my solution might not be very convenient after all: 
Popups are also closed after a page refresh, i.e. when zooming in. This 
may not be desirable. I think this is going to be a problem for a future 
popup manager as well. Unless a separate Close button is added to the 
application.
