        * gui/gdmlogin.c: Number of usability fixes for gdmlogin.c.  Now
          do not bother showing browser userlist widget if there are no
          users to display.  Now OK and Cancel buttons are set sensitive or
          insensitive based on context (OK only if something is in the entry
          field and Cancel if not on "Username" request).  Fixed bug causing
          face browser to autoselect first user.  I changed the behavior
          of how key events are listened to.  Now respond on release instead
          of press for accepting Tab key as Enter, back_prog delay,
          timed_login reset, and flexiserver reaping.  This made setting the
          buttons sensitive/insensitive easier.
