Subject: * cmdline/apt-get.cc:   - added "--fix-policy" option to make it easy
 to fix any not-install     recommends * apt-pkg/depcache.{cc,h}   -
 MarkInstall() has a new "ForceImportantDeps" option (defaults to false)    
 to fice the install of recommends even for already installed pkgs   - a new
 PolicyBroken() function to see how much of the recommends are     broken
