    app: set "OK" the default button to the "Create a New Image" dialog.
    
    In Linux, I never paid attention to it because it was already working as
    expected (i.e. Ctrl-n followed by Enter for instance would directly
    create the image), but when testing GIMP on Windows for the installer,
    these last few days, I realized that hitting Enter when focus was on the
    dimension entries was doing nothing. Having to move the pointer to click
    a button on Windows was frustrating. So let's make OK the official
    "default response" directive for this dialog.
