* grml-autoconfig script: deprecate CONFIG_KERNEL, CONFIG_LANGUAGE,

    CONFIG_DMA and CONFIG_MIXER as they are not really relevant on hd
    installations.
  * Do not use swap by default anymore, thanks for feedback goes to
    Wolfgang Karall!
  * Set mailaddress when creating /etc/mdadm/mdadm.conf so mdadm's
    initscripts do not report warnings anymore on hd-installations.
