More removal suggestions

[Moritz Muehlenhoff <jmm@inutil.org>]

Outdated documentation (Easily accessible online, outdated docs cause more harm
  than benefit):

autobook    - non-free, orphaned since 2005, newer release available, ITA w/o
              activity since januaray
ggi-doc     - docs are from 2004, while ggi versions in Debian are recent
bazaar-doc  - scheduled for removal in lenny (#454313), docs already orphaned
              and should be removed likewise
gnumail-doc - gnumail itself is at version 1.2, while the docs are still for 1.0 

Cheers,
        Moritz
