    keyboard: make Add button insensitive after editing
    
    When creating a new keyboard shortcut, the Add button gets
    sensitive when all the fields are valid. If the user tries
    to create a new shortcut right after closing the shortcut
    editor dialog, the Add button is still sensitive even with
    invalid custom fields.
    
    Fix that by making the Add button sensitive whenever we
    finish editing the new custom shortcut.
