Revision 750

   * Updated transition_db.pl to fix skipping of items with no owner.
     Closes: #88820
   * Documented in the user's guide that it needs apt-utils 0.5 or above for
     preconfiguration (really later, since that is currently broken in
     apt..) Closes: #88705
   * Made apt-extracttemplates be less scary if apt-utils is not installed.
     We really need a better solution here, I think..
   * Updated french translation from Martin Quinson <Martin.Quinson@ens-lyon.fr>
