    app, menus: add "Image -> Transform -> Arbitrary Rotation..." action
    
    Add a gimp-rotate-image-arbitrary action, and a corresponding
    "Image -> Transform -> Arbitrary Rotation..." menu entry, which
    activates the rotate tool in image mode (similarly to the
    corresponding action for layers).
