docstring: Sets the default action invoked on page-form submit
  
  This is necessary as the user may just press Enter instead of
  clicking one of the named submit buttons and then no action name will
  be passed to the script.
  
  @param  string    Default action name
  @param  string    Path to a 1x1 transparent GIF image
  @return object    Returns the image input used for default action
