David Capello 69d0564a09 Fix crash closing a MenuBox with viewport (fix #3132, fix #3133)
Regression introduced in ed595eb6b1
calling MenuBox::setMenu() of the first child of a MenuBoxWindow when
handling its kCloseMessage. The firstChild() was supposed to be a
MenuBox, but we didn't take care of the case when the MenuBox is
replaced with a View when scrollbars are needed (added by
add_scrollbars_if_needed()).
