    app: fix warnings and crashes in rectangle select and crop · ff915b68
    Michael Natterer authored
    We can't rely on g_object_unref() in halt() for breaking all property
    GBindings between the tool options and GimpToolRectangle, because we
    might be in the middle of a signal emission which also refs and keeps
    the rectangle alive until the last callback returns. So we had
    dangling rectangles interacting with tool options.
    
    Remember all bindings in a list, and break them explicitly when we
    shut down the rectangle in halt().
    
    Also, forgot to unset the display's highlight in the rectangle
    selection tool.
