2.13.0.4 stuff:

Interface Changes:

- This version of GDM handles its configuration files slighly differently.
  Now users are not recommended to modify the installed gdm.conf file and
  are instead encouraged to make changes to gdm.conf-custom.  The gdmsetup
  program now saves user configuration changes to the gdm.conf-custom file.
  Configuration options specified in gdm.conf-custom file override the values
  in the main gdm.conf file.  

  This allows distributions to overwrite the gdm.conf file without worry
  that the file contains any user customizations.  When running "make install"
  GDM now compares the already installed gdm.conf with the already installed
  factory-gdm.conf file and if they both exist and are not the same, then
  gdm.conf file is moved to gdm.conf-custom to preserve user changes.  If the
  gdm.conf-custom file already exists it is renamed to gdm.conf.org.
  Distributions should do the same when upgrading GDM.

  Note that this change is backwards compatible.  GDM will still work as
  it did before even if no gdm.conf-custom file exists on the system.

- gdmconfig no longer supports the --config command line option since it
  now accesses the configuration data over the sockets protocol rather
  than reading the configuration files directly.  Note the GDM daemon still
  supports the --config command line option.

- Added PostDisplayProgram and the --with-prefetch configuration option
  to support GDM running a prefetch script to preload libraries when it
  firsts starts the greeter program, which has been shown to improve first
  time login time.  (Padraig O'Briain, Brian Cameron)

- Add new priority configuration option for servers defined in the 
  [server-foo] section of the configuration files.  This can be set from
  -20 to +20 in order to specify the priority value given to the Xserver
  on startup.  (Philip Prindeville)

Other Changes:

- This release completes the internal redesign of GDM's configuration
  system.  Now all configuration information is read by the daemon and
  accessed via the GDM sockets protocol.  The GET_SERVER_LIST and
  GET_SERVER_DETAILS sockets commands were added to support accessing the
  [server-foo] sections of the configuration file via the sockets protocol.

- Merged code for parsing character sequences in gdmgreeter labels and
  the Welcome/RemoteWelcome keys, so now they are handled the same by both
  gdmlogin and gdmgreeter.  Now %d is used for display number and %s is the
  system name (uname.sysname).  The previously undocumented sequences are now
  explained in the documentation.  (Brian Cameron)

- Fixed bug that caused TimedLogin/AutomaticLogin to be turned on if it had a
  username value but TimedLoginEnable/AutomaticLoginEnable had a "false" 
  value.  (Brian Cameron)

- Fixed bug that caused the TimedLogin user to be logged in if the user
  hit the "ENTER" key without entering a password.  Mention in the GDM
  documentation that if the user does not enter a username but just hits
  the ENTER key while the login program is requesting the username, then 
  GDM will just login as the timed user.  (Brian Cameron)

- Removed libgnome as a GDM dependency and removed most libgnomeui 
  dependencies.  Redesigning GDM's configuration allowed GDM to stop using
  deprecated gnome_config interfaces, for example.  (Brian Cameron)

- Fixed a bug with keeping the sockets protocol open for multiple commands
  that was included in the last release, and fixed memory handling issues
  that was causing core dumping with gdmsetup in the previous release.
  (Brian Cameron)

- Fixed bug with the --with-configdir configure option.  (Brian Cameron)

- Now use glib stdio functions like g_chmod instead of chmod. 
  (Brian Cameron)

- Corrected typos and grammar (Brian Cameron, Asmund Skjaeveland, Adam
  Weinberger)
