2.13.0.2 stuff:

- Further redesign of configuration parsing logic.
  Now all GDM slaves (except gdmsetup) use the
  GET_CONFIG socket command to access configuration
  data.  This means all configuration parsing is now
  handled in one place, the daemon.  Improvements
  to the daemon configuration parsing so it
  correctly parses and validates all parameters used
  by the slave programs.  Also fix some compile
  issues that were causing problems with certain
  configurations.  (Brian Cameron)

- Improved the GET_CONFIG command so that you don't
  have to include the default value (you can use
  "greeter/IncludeAll" instead of having to use
  "greeter/IncludeAll=false".   Also you can 
  access keys that contain translatable strings
  (e.g. "greeter/Welcome[cs]") via the GET_CONFIG
  command.  (Brian Cameron)
  
- Changes to peeking VT freeness in 2.13.0.1 broke
  virtual terminal support on BSD.  This release
  corrects this problem.  (Brian Cameron)

- Correct Linux get VT logic so it returns the
  correct VT.  (Frederic Crozat)

- Now gdmlogin always uses GDK_RGB_DITHER_MAX
  when painting the background to ensure a nice
  background regardless of X configuration
  (e.g. X in 16bpp mode).  (Frederic Crozat)

- Now check for Xserver in prefix /usr.

- Fix configure for Darwin. (dmacks@netspace.org)

- Fix compiler warnings. (Frederic Crozat, 
  dmacks@netspace.org, Brian Cameron)

- Ensure gnome.desktop and default.desktop have
  644 perms.  (Andrew Benton)
