[gimp] app: Make "All images" mean all images in the file dialog

[Martin Nordholts <martinn src gnome org>]

commit 5317ff7490e725ea222b14efc6d13e6fae509099

    app: Make "All images" mean all images in the file dialog
    
    Even though a user can only save to XCF in File->Save, the "All
    images" filter shall show all images to allow a user to steal names
    from non-XCF images and vice versa for File->Export, so make that
    happen.
