gdm2 new strings

[George <jirka 5z com>]

Well not really new strings, old ones.  But you can finally translate them
now.  All the graphical greeter stuff has been set up to use intltool and
so you can go wild translating it.  (This is not really breaking the string
freeze, since those strings were there already:)

   There is nothing so useless as doing efficiently that
   which should not be done at all.
