gdm dconf changes

[Ray Strode <halfline gmail com>]

Hi,

GDM 3.2.0 uses dconf in a sort of weird way involving generating
binary dconf databases at build/install time in dummy dbus sessions.

I tried to improve that in GDM 3.2.1 by generating text keyfiles instead:

http://git.gnome.org/browse/gdm/commit/?id=25004e4

This second try was still a bit contrived and complicated for
distributors, so Vincent filed a bug:

https://bugzilla.gnome.org/show_bug.cgi?id=662168

I've now done a GDM 3.2.1.1 release that dramatically simplifies how
GDM does settings:

http://git.gnome.org/browse/gdm/commit/?id=c0416390

With this change, though, distributors do need to remember to run
"dconf update" as part of their packaging post transaction hooks.

Just a heads up,
--Ray
