2.13.0.7 stuff:

- Turns out the core dumping issue that was supposed to be fixed in 2.13.0.6
  wasn't really fixed.  Now it is.  (Sebastien Bacher)

- New "options_button" available for gdmgreeter themes.  This pops up 
  the F10 menu which has all the choices found in the Disconnect, System,
  Sessions, and Language buttons so that themes can have a cleaner 
  1-button look.  The default circles, happygnome, and happygnome-list
  themes now use this style.  (Sebastien Bacher, Brian Cameron)

- Fix bugs that were causing User24HourClock=auto to not work properly.
  Now GDM should properly grab the system time format when auto is set.
  (Christopher Aillon)

- Fix bug in PreSession script that was causing it to not properly set the
  background color before starting user session.

- GDM docs now has a troubleshooting section.  (Brian Cameron)

- Make sure /usr/openwin/bin is in PATH on Solaris, since this is needed
  for PreSession/PostSession scripts to find sessreg and other needed
  X programs.

- String change of "XDMCP Chooser" to "Remote Login via XDMCP".
  (Brian Cameron)

- Minor tweaks to default/example gdmprefetchlist file so it works 
  better for GNOME 2.14 out of the box.

- Translation updates (Stanislav Brabec, Theppitak Karoonboonyanan,
