[kupfer] Add 'Close' action on AppLeaves to close all windows

[Ulrik Sverdrup <usverdrup src gnome org>]

commit 64bee1b464479bc8082ce1b6f948c6774ab6500d

    Add 'Close' action on AppLeaves to close all windows
    
    We use window matching to try to find all windows of the app and call
    close on them.
    
    There is no Application API on Linux, which is sad. We can't call this
    action Quit; we have no way to quit an application in general. Many
    applications will quit if we close all windows, but far from all.
    Calling this action "Close" will catch the concept.
