Dialog close button

[Terence Ferraro <terencejferraro gmail com>]

Not sure if anyone else will find this of use, but, as of 3.12 a titlebar is provided for back-ends that do not provide their own (e.g. Broadway) and are quite sleek. Broadway made the shift to this at the same time away from client side decorations. Regular windows show the close button; dialogs do not. Not really sure if that's intentional, but...

The attached diff adds such a close button by default to a dialog (code mostly borrowed from gtkwindow.c).
