SKILL           "set a mobiles knowledge in a certain skill"

  skill         full name of the relating skill (e.g.: bashing)
  knowledge     knowledge % in that relating skill (e.g.: 100)

  
  Notes:
  * for the skills 'sneaking', 'climbing' and 'swimming' the relating flag is
    turned on, so the mobile will actually sneak, climb or swim.
  * mobiles of type 'fish' are already flagged with swimming skill, so it does
    not need to be set for them
