    Move Shutdown functions to panel instead of login window
    
    Robert Ancell gives a good rationale for the move:
    "In GDM 2.28/master on startup the user is presented with a window
    containing:
    - A list of users to log in as with the first user selected
    - Two buttons, restart and shutdown, below the user list
    
    Since the first user is selected, users who are unfamiliar/not paying
    close attention sometimes click on the shutdown button as this is placed
    where the default action (in this case login) is conventionally placed
    (the lower right hand corner of the window).  The penalty of making this
    mistake is for the computer to shut down immediately with no chance of
    aborting this mistake.
    
    An additional mistake users can make is to miss clicking on their user
    and then click on the shutdown button (as this button is replaced with
    the login button after selecting a user).
    
    Recommended behaviour:
    
    Move the shutdown actions (shutdown, sleep, hibernate, restart) to a
    menu on the GDM panel.
    
    The shutdown buttons do not need to be prominently located as:
    - They are used less frequently than the login buttons (normal operation
      is to shutdown from within your session).
    - Most hardware has a dedicated power button that performs the same
      action
    - It is better to have them in a location where they are less likely to
      be accidentally activated"
