    keybindings: fix erratic raise_or_lower behavior
    
    Function "handle_raise_or_lower (src/core/keybindings.c)" is called
    when running 'raise-or-lower' on a window. This function iterates
    through all the windows in the stack to determine if our window is
    already on top or obscured. The problem is that the window stack
    includes windows in another workspaces and also windows that are
    minimized.
