FAI release 2.6.7

[Thomas Lange]

FAI 2.6.7 only includes a minor (?) update. Support for preseeding
debconf data is now implemented. Therefore the new task debconf was
created. Have a look at fai-debconf(8) for more details. Currently the
examples inside FAI do not use debconf preseeding.

New in FAI 2.6.7

    - add task debconf and new script fai-debconf for preseeding
    - minor updates in the fai guide
